3. BITSAT Test Details
‘Computer Based Online test’ means the candidate sits in front of a computer and the questions are presented on the computer monitor and the candidate submits the answers through the use of key board or mouse. Each computer is connected to a server which prepares the question set and delivers it to the candidate on the computer. This is unlike the traditional paper-pencil based test which is generally offered on a single day to all candidates. BITSAT-2008 will be offered over a period of time and the candidate can choose the center, the day and time of his/her convenience to take the test, as described in the later sections.
BITSAT-2008 Test Format
BITSAT-2008 will be of total 3 hour duration (without break). The test consists of four parts:
Part I : Physics
Part II : Chemistry
Part III : (a) English Proficiency and (b) Logical Reasoning
Part IV : Mathematics OR Biology
Students who have taken Mathematics and not Biology in 10+2 have to appear for Mathematics in Part IV. Students who have taken Biology in 10+2 and not Mathematics have to appear for Biology in Part IV. Students who have taken both Mathematics and Biology in 10+2 can opt for either Mathematics or Biology in Part IV. Candidates who appear in Biology in Part IV will be eligible for admission to M.Sc. (Hons.) Biological Sciences and B.Pharm. (Hons.) only. Candidates who appear in Mathematics in Part IV will be eligible for admission to any of the Integrated First degree programmes, including M.Sc.(Hons.) Biological Sciences and B.Pharm.( Hons.).
All questions are of objective type (multiple choice questions); each question with choice of four answers, only one being correct choice. Each correct answer fetches 3 marks, while each incorrect answer has a penalty of 1 mark. No marks are awarded for not attempted questions. While the candidate can skip a question, the computer will not allow the candidate to choose more than one option as correct answer.
There will be 150 questions in all. The number of questions in each part is as follows:
Subject
No of questions
Part I
Physics
40
Part II
Chemistry
40
Part III
(a) English Proficiency
(b) Logical Reasoning
15
10
Part IV
Mathematics OR Biology
45
Total:
150
There is no time limit for individual parts of the test. The candidate can go back and change any of his/her answers among the 150 questions.
If a candidate answers all the 150 questions (without skipping any question), the candidate will have an option of attempting 12 (twelve) extra questions, if there is still time left. These extra questions will be from Physics, Chemistry, Mathematics / Biology only; four questions from each part. Further, once the candidate has opted for extra questions, he can not go back for correction of any of the earlier answered 150 questions.
The questions are so designed that a good student will be able to answer 150 questions in 180 minutes. The extra questions (a maximum of 12) will give a chance to highly meritorious candidates to score higher. However, candidates should keep in mind the fact that there is negative marking for wrong answers and any attempt to answer the questions by pure guessing of the answers is not likely to have any advantage, but may result in a reduction in the total score.
The questions will be selected at random from a large question bank. Different candidates will get different question sets. An expert committee will ensure that the question sets are of comparable difficulty level, content, question type etc. In this matter, the decision of the expert committee will be final and binding on the candidate.
All the questions and instructions of the test will be in English only.
Each candidate who registers for BITSAT-2008 will be issued a ‘Hall Ticket’. Candidates with the hall ticket only will be allowed inside the test centers. Candidates should bring a pen for the purpose of rough work, signing etc. Blank sheets for rough work will be provided, if required. Calculators and logarithmic tables are not allowed in the test centers. Candidates are not allowed to bring any other personal belongings such as mobiles.
All centers are closely monitored for security and candidates’ identity and activities will be recorded using web cameras and/or closed circuit TV cameras. Anyone violating the rules of the test center will not be allowed to continue with the test and will be automatically disqualified.
BITSAT 2008 Syllabus:
The BITSAT-2008 test will be conducted on the basis of NCERT syllabus for 11th and 12th class. The detailed syllabus is given in the Annexure. Candidates may refer to the NCERT text books for the contents. A sample test will be made available to the registered candidates at the BITS website on which he/she can practice as many times as desired.

Goiit Gives IIT JEE Tutorials Online
Students preparing for IIT and other engineering entrance exams now have help from the online medium.
Noida-based Vriti Education has launched Goiit.com, an online education portal to serve as a platform for students preparing for their Joint Entrance Examination (JEE) as well as other competitive entrance exams like AIEEE, BITSAT, WBJEE, etc.
What is interesting about the venture is that it comes for free, sans subscription fees, and is intended as a huge advantage for the student community.
Developed by alumni of IIT Mumbai and IIT Delhi, Goiit.com will provide engineering aspirants with expert advice and guidance through an expert panel comprising IIT students, graduates, and engineering coaching professionals.
The portal intends to bring together students, teachers, and the IIT community in general so that they can collectively put some of the best brains in the business to constructive use.
Swapnil Shrivastav, chief executive officer of Goiit.com, said Goiit comes as a great advantage for students who've been craving for personalized help but cannot afford it due to cost or demographics.
Shrivastav voiced the view that from Gurukul to online mode, education has come a long way to become an ever-changing sector -- now breaching geographical boundaries to reach out to people across the globe.
Pankaj Vermani, vice president of Goiit.com, said Goiit is possibly the only Web site (and supposedly a 'cool' one) that gives a unique platform for engineering aspirants to prepare for JEE, and use the online community, forum, online tutorials, study materials, and all of that for free.
As of now, Goiit has a 50-strong team, made up of IIT alumni, engineering graduates, and engineering coaching professionals.

---------------
electrochemical cell
or Voltaic or Galvanic Cells
In this cell, a chemical reaction produces electrical energy.
In this cell, the electrons being transferred from the reducing agent to the oxidizing agent travel through a wire and thus provide an elctric current.
a electrochemical cell is represented as
Ө Zn|ZnSO-4║CuSO-4|Cu In this symbol additionally On zinc side as it is a cathode a - sign is placed in O (as shown) and on Cu side as it is anode a + sign is placed in O.
cell reactions;
Reaction at the electrodes are called half cell reactions as both the elctrodes are kept seperate from physical contact and ion movement only is permitted through salt bridge.
At zinc electrode Zn → Zn^2+ +2e¯ (oxidation)
At Cu electrode: Cu^2+ +2e¯ → Cu (reduction)
Electrode potentials
When an electrode in put in solution of ions, a charge is developed between the solution and the electrode. This charge is termed a electrode potential. The electrode potential cannot be measured individually and it is measured in reference to a standard hydrogen electrode.
Standard Hydrogen Electrode
An electrode in which pure dry hydrogen gas is bubbled at 1 atm and 298K about a platinized platinum plate through a solution containing H^+ ions ( for example - HCl solution)
The emf produced is taken as zero volts. All other potential are expressed with SHE potential as zero.
Nernst Equation: The cell potential of a half cell (as well as that of a complete cell) depends upon the concentrations of involved ions, pressure of the gaseous species (if involved) and the temperature. The relation connecting them is given by the Nernst equation.
It is expressed as
E = E° - (RT/nF)ln Q°
Q° = Product of concentration (or pressure) of products each raised to the corresponding stochiometric number/Product of concentration (or pressure) of reactants each raised to the corresponding stochiometric number
n = number of electrons involved in the hall cell reaction
Electrochemical series is the series in which various elements are arranged in the order of their reduction or oxidation potentials.
Emf of galvanic cells
E(Cell) = E(R) - E(L)
Electrolysis
In electrolytic cell, electric energy is used to cause a chemical reaction to take place.

Faraday's laws of electrolysis:
---------------------------------------
Quantitative Relationships in Electrolytic Cells
Determining the amount of electrical energy necessary for accumulating a given amount material from the electrolytic cell.
First law: It states that the amount of any substance that is liberated at an electrode during electrolysis is directly proportional to the quantity of electricity passed through the electrolyte.
W α Q (w = weight of substance deposited and Q is charge = ampere * time)
Second law: It states tht when the same quantity of electricity is passed through different electrolytes amount of different substances liberated or deposited at the different electrodes are directly proportional to the chemical equivalents9i.e., equivalent weight) of substances.
One faraday (F) is the amount of electrical energy required for flow of 1 mole of electrons.
To three significant digits, 1 faraday equals 96,500 coulombs(coul).
Current flow is measured in amperes (A)which is coulombs/seconds or coul/s,
Electrolytic conductance
The flow of electric current through an electrolytic solution is known as electrolytic conduction.
Electrolytic conduction also follows Ohm's law.
The equivalent conductivity of an electrolyte may be defined as the conductance of a volume of solution containing one equivalent mass of a dissolved substance when placed between two parallel electrodes which are at a unit distance apart, and large enough to contain between them the whole solution.
The molar conductivity of a solution gives the conducting power of ions produced by one molar mass of an electrolyte at any particular concentration.
Kohlrausch's Law on the independence of migrating ions: The molar conductivity of an electrolyte equals the sum of the molar conductivities of the cations and the anions; n = number of anions or cations.
Λ = v+Λ+ + vˉΛˉ
Concentration cells.
Concentration Cells are electrochemical cells that have two equivalent half-cells of the same material differing only in concentrations. One can calculate the potential developed by such cells using the Nernst Equation. A concentration cell produces a voltage in the process of reaching equilibrium, which will occur when the concentration in both cells are equal.
Concentration cell methods of chemical analysis compare a solution of known concentration with an unknown, determining the concentration of the unknown via the Nernst Equation.

If Tomorrow Never Comes…
If Tomorrow Never Comes…
As much as I wish for it not to come, it dead sure will.
Tomorrow is one day I’m not exactly looking forward to because it’s the day I’m going to have my chemistry board practical. Doesn’t sound like much of a deal does it? Wait then, let me just do some font formatting to give you a better idea. Here goes – Tomorrow, I have my Chemistry BOARD Practical. Get it now? Eh?
I’m really bad at sticking to the things I say. Just in the last post I said I was going to go into hibernation mode and here I am, making another post. And I’ve not even ventured close to hibernation mode. In fact I’ve actually become more active on Facebook than I’ve ever been. Not a really good sign is it? As if I care anyway. So yeah, tomorrow is the chemistry board practical in which I will have to do a volumetric analysis in which basically you have to let some liquid drop from one tube into a beaker and wait for the colour of the shit in the beaker to change. Then you note down the amount of liquid dropped from the tube and perform a couple of useless calculations. The other [and much more dreaded] thing I’ll be made to do is salt analysis. Basically I’ll be given a compound and I’ll have to put whatever I can find into it to get some weird colour or gas that will burn my nose hair. Eternal bliss, I tell you. I’m not particularly fond of this because I’m terrible at it. I’m impatient and whenever I don’t get any positive tests on my first attempt, I panic and give up. And considering that I have a 100% failure record in it, I’m not feeling very confident. Also, my chemistry teacher is such a character. I had to give a retest because I did badly in my original chemistry exam. I passed in the retest [to my absolute horror cause I thought I was gonna fail royally] but still I’ll be made to give a re-retest. So I went to the teacher to ask him why I was being made to give a retest when I’d already passed in this. He said, “Well, this test was very easy and still you’re just barely passing, so you have to give it again.” I was pretty much on the verge of saying that, “Dude, I’ve not got even 20% marks in your subject in the last year or so..and here I am, getting over 40%(33% is passing) but still I’m being called a failure. What is the deal with you? Why can’t you let me be confident about myself for once?” But I knew it’d be useless so I didn’t elaborate any further.
Also, amongst other things, I came to know that a daughter of one of my mother’s cousins met with a bad accident. Now, I’ve never seen that girl, don’t know her name but still I feel very bad for her. I can’t understand why exactly. But maybe it’s just because when her mother was talking to my mother, she was more concerned about the girl missing her class 11th exams and ruining her chance of getting into a good entrance examination. And I was like..what the hell? How can anybody be concerned about studies right now..the girl just escaped death almost. A tractor was just about to go over her face but it scraped some side of her face and it got damaged and all that. And still people were concerned about studies? I may be interpreting this in an entirely wrong fashion but it was weird to me. I’m sure her mother cares about her and all..maybe it’s just that I’m too touchy with people who have kids doing the same subjects that I am and running from one coaching centre to another to achieve success in the IIT-JEE and the AIEEE. It reminds me of how I’ve literally wasted the last two years of my life. Agreed there’s competition everywhere but this system is just not correct. Whatever anyone might try to explain, it’s not justified. Anyhow, I’m not gonna get into all that because this is just not the time to crib about the system. So, I hope you get well soon, my anonymous cousin and may you achieve success in whatever you wish to do. In other words, I hope you have the Time of Your Life.
Okay, time to go back to my dear Mr. Sulphuric Acid, Mrs. Hydrochloric Acid and their kids, Masters Oxalic Acid and Phosphoric Acid. I genuinely hope I don’t end up throwing one of you on the external examiner’s face. Peace.
Update - 4/2/2008
So, the practical is done and it wasn’t as bad as I thought it would be. I managed to do the written part neatly and also managed to do the titration and the salt analysis. They had told us which salt we were gonna get so it wasn’t a big deal. But hey, at least I didn’t have to ask anybody to tell me the confirmatory tests, I had learned those this time around.
The external didn’t look like a happy woman to me. She was a total disaster. She was looking like this mean looking woman with a hunter, leather clothes and high heels who would kill you if you didn’t answer the questions. Well of course, she wasn’t having a hunter and wasn’t wearing leather, but she was wearing heels and was looking mean and khadoos. And my not knowing anything didn’t really help. I thought my Viva was really funny. Here’s how it went:-
Teacher - Formula of Fehlings solution A and B?
Me- I don’t know.
Teacher - Formula of Benedict’s reagent?
Me - I don’t know.
Teacher - What is the structure of the functional group anhydride?
Me - Anhydride functional group? Isn’t it when you remove water from something?
Teacher - Huh.
Teacher - How do we prepare Hydrogen Sulphide by Kipps process?
Me - I don’t know.
Teacher - Didn’t you pass Hydrogen Sulphide during your salt analysis?
Me - Nope.
Teacher - What salt are you having?
Me - Aluminum Nitrate (haha, thanks teachers!)
Teacher - How come you came to know that without passing H2S?
Me - Uhh..I guessed?
Teacher - What is the formula of Aluminum Nitrate?
Me - Al(NO3)3 (Lol, if my teacher hadn’t written that on the board today, I was gonna give another “I don’t know”).
Teacher - Okay go.
Me(to myself) - LOL, what a disaster! :))

IIT JEE Revision Ch. 6 ENERGETICS Core Points
IIT JEE Revision Ch. 6 ENERGETICS Core Points
JEE Syllabus
Energetics:
First law of thermodynamics;
Internal energy, work and heat,
pressure-volume work;
Enthalpy,
Hess's law;
Heat of reaction, fusion and vapourization;
Second law of thermodynamics;
Entropy;
Free energy;
Criterion of spontaneity.
------------------
First law of thermodynamics;
Energy cannot be created or destroyed.
U = q + w
Internal energy of matter is equal to kinetic energy and potential energy.
The change in internal energy is equal to heat transferred and work done between the system and the surroundings.
Pressure volume work: If the pressure is constant and the matter expands, the work done is given by p * change in volume. This in termed as pressure volume work.
Enthalpy = U + pv
Hess's Law
Hess's Law states that the enthalpy change for a reaction that occurs in many steps is the same as if it occurred in one step. Another way to put this is if several reactions add up to some total reaction, then their enthalpy changes will add up to the enthalpy change for the total reaction.
Second law of thermodynamics
In general it is impossible to perform a transformation whose only final result is to convert into useful work heat extracted from a source that is at the same temperature throughout. This statement is Lord Kelvin's version of the second law of thermodynamics.
Another version of this law, formulated by R. J. E. Clausius, states that a transformation is impossible whose only final result is to transfer heat from a body at a given temperature to a body at higher temperature; in other words, the spontaneous flow of heat from hot to cold bodies is reversible only with the expenditure of mechanical or other nonthermal energy.
The Second law of Thermodynamics states that every spontaneous change is accompanied by an increase in entropy which is a measure of the randomness or disorder of a system.
For each topic in the JEE syllabus detailed revision points are posted in the following posts.

IIT JEE Revision Addition reactions of alkynes
IIT JEE Revision Addition reactions of alkynes
The alkynes have at least one triple bond in them, therefore, they are quite reactive chemically.
They readily take part in addition reactions and can also be easily oxidized.
I. Addition reactions (specially given in jee syllabus)
1. Addition of Hydrogen
If the triple bond is not present at the end of the chain of the molecule (it is not a terminal alkyne), its reduction (addition of hydrogen) produces either a cis alkene or a trans alkene depending upon the choice of reducing agent.
2. Addition of halogens
chlorine and bromine add on alkali
3. Addition of hydrogen halides
This addition takes place in accordance with Markonikov's rule(do you remember the rule?).
Peroxides have the same effect on addition of the HBr to acetylenes (alkynes) as they have on alkenes (do you remember the effect?).
4. Addition of water (hydration of alkynes) (specially given in jee syllabus)
In the presence of acid (H2SO4) and HgSO-4, a molecule of water adds to the triple bond at 348K. The catalyst in this reaction is HgSO4 (Mercuric sulphate). The final products of this reaction are carbonyl compounds aldehydes and ketones.
Initially enol is formed which is raidly converted into an equilibrium mixture containing keto form in excess. Enol is so called because it contains 'ene' (double bond) and an alcoholic group (ol).
Examples:
Addition of water to Ethyne or acytelene: Acetylene is passed into water (at about 330K) containing 60% H2SO4 and about 1% mercuric sulphate (HgSO4) as a catalyst, acetaldehyde is formed.
In the first step 'ethenol' is formed and in the second step the rearrangement of it takes place and its isomer 'acetaldehyde' is formed.
The conversion of enol form into keto form is termed tautomerism
5. Addition of hypohalous acid (HOX)
Alkynes react with two molecules of hypohalous acids in two stages.
For example take ethyne or acytelene and HOCl.
In the first stage HO gets added to one carbon and Cl adds to the other carbon.
In the second stage one more HOCl gets added to the intermediate product which has a double bond. The addition now follows markonikov's rule. OH gets added to HC-OH and Cl gets added to CH-Cl. Two OHs create instability and H2O molecule gets removed.
An aldehyde 2,2-Dichloroethanal (Dichloroacetaldehyde) is formed.
6. Addition of H2SO4
Acetylene adds two molecules of concentrated H2SO4 in two stages and forms ethylidene hydrogen sulphate as the final product.
In the first stage Vinylhydrogen sulphate H2C=CH-OSO3H is formed. (H gets added to one CH and OSO3H gets added to the other CH).
The addition of second molecule follows markownikov's rule. H gets added to CH2 and OSO3 gets added to the other carbon. Thus two functional groups OSO3H gets added to one carbon.
The final product is Ethylidine hydrogen sulphate.

Alekenes Chemical Properties
Alekenes Chemical Properties
Topics mentioned specifically in JEE syllabus are covered in separate posts
Addition of sulphuric acid
Coldi and concentrated sulphuric acid adds to alkenes forming alkyl hydrogen sulphate.
This adds to water to give alcohol. Actually the final reaction is same as acid catalysied hydration of alkenes.

IIT aspirants up in Andhra Pradesh
IIT aspirants up in Andhra Pradesh
The number of students from the state who are trying to get into Indian Institute of Technology has increased by 25 per cent when compared to last year.
While nearly 39,000 candidates had applied for Joint Entrance Examination in 2007, the number went up to about 50,100 this year. Last year, over 500 students from the state secured seats in various IITs.
The JEE-2008 for admission to various undergraduate courses in the seven IIT's and other technological universities of the country will be held on April 13. The last date for submitting application forms ended on January 4.
"There has been more than 25 per cent increase in the number of applicants across the country and not just in Andhra Pradesh," said Mr N.M. Bhandari, chairman of JEE-2008.
Last year, 2.43 lakh students had appeared for the test and one lakh more students have applied for JEE-2008. The number of students competing for a seat has gone up to 77 while it was 55 last year.
There are nearly 4,500 seats available in the seven IITs across the country.
"The number of students competing for a seat in prestigious global universities such as Harvard and Massachusetts Institute of Technology is eight," said Mr Bhandari.
"The competition for IITs is tougher."
Veteran IIT trainer and MLC, Mr Chukka Ramaiah, said the drop in standards and lack of faculty and infrastructure in most engineering colleges of the state had forced students to opt for IITs.
"Most of the engineering colleges in the state produce graduates who are unemployable," he said. "They are forced to undergo training in Jawahar Knowledge Centres to develop skills."
Meanwhile, the newly announced IIT at Medak may not start functioning from this year.

The softer side of IIT_JEE's toughness
The softer side of IIT_JEE's toughness
The IITs declared the results of supposedly, the world’s toughest entrance exam to crack – the IIT JEE, on the 30th of May this year. Almost all the newspapers carried full-page coverage of the news, including even the male-female statistical break-up of qualified students; and of course smiling photographs of jubilant toppers who have made their parents, schools and cities proud. Out of a whopping 243039 takers, 8635 managed to qualify for the rankings to make it to the coveted IITs (including 587 girls, a fact lauded by the media seeing their dropping numbers all through these years).
We will all read these stories, congratulate those who made it with high ranks and the toppers will bask in this newfound glory for a long time to come. Do we ever realize that even if we assume 100,000 students appearing for the JEE seriously, more than 95,000 students will not make it to the IITs? Statistically, this gives a success rate of just 5% (and only 2% if we include all those appearing). Does anyone write anything in the papers for them? No, because it is only the toppers who deserve to be lauded, don’t they?
In the JEE world, there is break-neck competition, not to mention the tremendous pressure to succeed. While we may say that those buckling under pressure never deserved to get in, having appeared for JEE myself twice and having not made it to the IITs, I can tell you that not answering a couple of questions in the exam can throw you distantly out of the race. Surely, pressure has little to do in such a scenario. In such a situation, is it that those who miss it by a whisker or even a couple of them are not worthy of the best engineering education in the country? No, because JEE as an exam cannot decide their merit, currently. Only scholastic measurement of a student’s intelligence (which is how JEE tests prospective students) cannot serve as the best indicator of the personality of a student, the understanding of which is essential to determine whether a particular engineering stream is suited for him / her.
It is time the JEE changes its pattern, not only to reduce the stress the students take on themselves, but more so to ensure that the best minds, not merely those who can rattle off derivatives / integration sums in seconds or those who can reproduce electro-magnetism sums verbatim from the notes of the coaching classes in the so-called “Mecca of JEE training”. The CAT (for IIMs) has interviews and group discussions as an integral part of its selection process. Just as the country needs its best managers from the IIMs, the IITs were established to produce the best engineers. Instances of students having made it to the IITs and then committing suicide for not being able to cope up with the pressure have featured recently. On top of that, “coaching centers” whose only aim is to equip students to crack JEE, succeed in getting students inside the IITs, but without the necessary aptitude to succeed in their curricula. JEE must ensure that not only scholastic aptitude, but an attitude and personality match is also equally important for an IITan, which if not considered, will not only spoil lives of those unable to withstand the strain, but will also not allow deserving others a chance to get the best engineering education in the country.
The point here is two-fold; firstly, not all the best students make it to the IITs; and secondly those who deserved but didn’t, need not panic or worry. IIT is not the end of the world (an oft quoted phrase now). I won’t give examples of how many IITans (and how many non-IITans) have made it big in this world, as I believe it has been repeated ad nauseum. The power is within you. Remember Eklavya’s story, who became the best archer without the best teacher beside him. IIT may not be with you, but you don’t be without it. Of course you will miss the other part of the grind: the countless nights spent together with friends playing basketball, the mesmerizing IIT campuses etc. But such is life my dear friend. Good education is absolutely essential; but forget not the most important factor in life: to be a good human being.
Bottom-line: Be the Eklavya in your life; and the world is yours.

IIt JEE Revision - Emulsions, Surfactants and Micelles
IIt JEE Revision - Emulsions, Surfactants and Micelles
JEE syllabus
Elementary ideas of emulsions, surfactants and micelles (only definitions and examples).
Emulsions:
Emulsion is a liquid dispersed in a liquid.
Any two immiscible liquids form an emulsion.
For example, milk is a naturally occuring emulsion in which particles of liquid fats are dispersed in water.
Since two immiscible liquids do not mix well, the emulsion is generally unstable and separation of liquids may take place on standing for some time.
Emulsifiers are substances which are added to make emulsions more stable.
Emulsifiers reduce the interfacial tension between the two liquids.
Two types of emulsions: Oil in water and water in oil.
Identifications of two types of emulsions:
Dilution test: If on addition of water, the emulsion becomes dilute, it means it is oil in water emulsion.
Dye test: An oil soluble dye is used and if the whole solution becomes coloured it is water in oil emulsion. If only drops become coloured, it is oil in water emulsion.
Any substance which can decrease the surface tension of water to a large extent is known as surfactant. Examples of soap and detergents. Such substances have larger concentrations at the surface of water as compared to the bulk of the solution.
Surfactants in solution are often association colloids, that is, they tend to form aggregates of colloidal dimensions, which exist in equilibrium with the molecules or ions from which they are formed. Such aggregates are termed micelles.

IIT JEE Revision Ch. 11. SURFACE CHEMISTRY Core Points
IIT JEE Revision Ch. 11. SURFACE CHEMISTRY Core Points
JEE syllabus
Surface chemistry:
Elementary concepts of adsorption (excluding adsorption isotherms);
Colloids: types, methods of preparation and general properties;
Elementary ideas of emulsions, surfactants and micelles (only definitions and examples).
--------------
The term adsorption implies the presence of excess concentration of any particular component in one of the three phases of matter (known as adsorbate) at the surface of liquid or solid phase (known as adsorbent) as compared to that present in the bulk of the material.
On the basis of the forces of attraction between adsorbent and adsorbate, two types of adsorption, namely, physisorption (i.e. physical adsorption) and chemisorption, may be identified.
Colloids or sols are the substances whose sizes lie in between the solutes present in a true solution (e.g., salt, sugar) and the solutes present in suspension (e.g., sand).
The diameters of colloidal particles may range from 1 to 100 nm. The particles in colloidal state do not settle down on standing, are not visible and they can pass through a filter paper. However, they do not pass through a perchment paper or animal membrane.
Emulsion is a liquid dispersed in a liquid.
Any substance which can decrease the surface tension of water to a large extent is known as surfactant. Examples of soap and detergents. Such substances have larger concentrations at the surface of water as compared to the bulk of the solution.
Surfactants in solution are often association colloids, that is, they tend to form aggregates of colloidal dimensions, which exist in equilibrium with the molecules or ions from which they are formed. Such aggregates are termed micelles.

IIT JEE Revision Molecular weight - freezing point.
IIT JEE Revision Molecular weight - freezing point.
Molecular weight determination from depression of freezing point.
The freezing point is the temperature at which the solid and liquid states the substance have the same vapour pressure.
When a non-volatile solute is added to a solvent, the freezing point of the solution is always lower than that of the pure solvent.
The depression in freezing temperature is proportional to the molal concentration of the solution (m).
ΔTf α m Or ΔTf = Kf*m
ΔTf = depression in freezing point.
Kf is the molal depression constant. also called molal cryoscopic constant. It is defined as the depression in freezing point for 1 molal solution i.e., a solution containing 1 gram mole of solute dissolved in 1000 g of solvent.
When m =1; ΔTf = Kf
Depression in freezing point is a colligatvie property as it is directly proportional to the molar concentration of the solute.
To find the molar mass of an unknown substance (nonvolatile compound), a known mass of it is dissolved in a known mass of a solvent and depression in its freezing point (ΔTf)is measured.
weight of solute be Wb g
weight of the solvent be Wa g
Molar mass of the solute be Mb
Molality of the solution, m = Wb*1000/Mb*Wa
Substitute the value of m in ΔTf = Kf*m = Kf*Wb*1000/Mb*Wa
From the above equation Mb can be calculated.
Mb = Kf*Wb*1000/Wa*ΔTf
Example:
Addition of 0.643 g of a compound to 50 ml of benzene (density 0.879 g/ml) lowers the freezing point from 5.51°C to 5.03°C. If Kf for benzene is 5.12 K kg molˉ¹, calculate the molar mass of the compound. (IIT 1992)
The formula of Mb is available above.
weight of solute be Wb g = 0.643 g
weight of the solvent be Wa g = 50*0.879 = 43.95 g
Change in freezing point = 5.51 - 5.03 = 0.48°C
Mb = (5.12 * 0.643 * 1000)/(43.95*0.48)
Mb = [Kf*Wb*1000]/[ΔTf * Wa]

IIT JEE Revision Ch 9. SOLUTIONS - Core Points
Jee Syllabus
Solutions:
Raoult's law;
Molecular weight determination from lowering of vapor pressure,
Molecular weight determination from elevation of boiling point
Molecular weight determination from depression of freezing point.
-----------------
Raolt's Law
In the case of a solution of two liquids, A and B, the total vapor pressure Ptot(P total) above the solution is equal to the sum of the vapor pressures of the two components, PA and PB and
PA = PA° * Am
PB = PB° * Bm
Where
PA° = vapour pressure created by 1 mol of liquid A
Am = mole fraction of liquid A in the solution
PB° = vapour pressure created by 1 mol of liquid A
Bm = mole fraction of liquid A in the solution
The pressure exerted by the vapours above the liquid surface in equilibrium with the liquid at a given temperature is called vapour pressure.
If a small amount of non-volatile solute is added to the the solvent, the vapour pressure of the solution becomes less than that of the pure solvent.
Some properties of the solution depend only on the number of solute particles but on the nature of the solute. These are called colligative properties or democratic properties.
The four important ones are:
i) Relative lowering in vapour pressure
ii) elevation in boiling point
iii) depression in freezing point
iv) osmotic pressure
Molecular weight determination from lowering of vapor pressure
Molar mass of a solute can be found from the property of lowering of vapor pressure of a solution.
Mb = (Wb*Ma)/[Wa*(Pa°-Pa)/Pa°]
Wb = weight of solute particles, Wa= weight of solvent
(Pa°-Pa)/Pa° = decrease in vapour pressure of solution
Ma = Molar mass of solvent
Molecular weight determination from elevation of boiling point
Mb = [Kb*Wb*1000]/[ΔTb*Wa]
ΔTb = increase in boiling point of the solution after adding the solute
Kb = molal elevation constant or ebulloscopic constant
= the elevation in boiling point for 1 molal solution, i.e., a solution containing 1 gram mole of solute dissolved in 1000 g of the solvent.
Molecular weight determination from depression of freezing point.
when a non-volatile solute is added to a solvent, the freezing point of the solution is always lower than that of the pure solvent.
The depression in freezing temperature is proportional to the molal concentration of the solution.
ΔTf α m Or ΔTf = Kf*m
Kf is the molal depression constant. also called molal cryoscopic constant. It is defined as the depression in freezing point for 1 molal solution i.e., a solution containing 1 gram mole of solute dissolved in 1000 g of solvent.
Mb = [Kf*Wb*1000]/[ΔTf * Wa]

IIT JEE
Allotrope
• Allotropes are elements that can exist in two or more different physical forms
• Diamond, graphite and buckminster fullerine are allotropes of carbon.
• The allotropes of carbon are all the element carbon. The type of carbon is determined from the bonding that occurs.
The carbon atoms in graphite are arranged in flat sheets that slide easily over each other, while the atoms in diamond are bonded in a complex, honeycombed structure that makes the solid much harder.
