In that, a paragraph will be given, and then the MCQ questions based on it will be asked. Solutions Case Study Questions With answers Here, we have provided case-based/passage-based questions for Class 12 Chemistry Chapter 2 Solutions Case Study/Passage-Based Questions Case Study 1: At 298 K, the vapour pressure of pure benzene, C 6H 6 is 0.256 bar and the vapour pressure of pure toluene C 6H 5CH 3 is 0.0925 bar. Two mixtures were prepared as follows: (i) 7.8 g of C 6H 6 + 9.2 g of toluene (ii) 3.9 g of C 6H 6 + 13.8 g of toluene The following questions are multiple-choice questions. Choose the most appropriate answer: (i) The total vapour pressure (bar...

1. (i)On mixing liquid X and liquid Y, the volume of the resulting solution increases. What type of deviation from Raoult’s law is shown by the resulting solution? What change in temperature would you observe after mixing liquids X and Y? (ii) How can the direction of osmosis be reversed? Write one use of reverse osmosis. Answer: (i) Positive deviation. The temperature will decrease. (ii) When we apply pressure on solution side more than osmotic pressure, osmosis can be reversed. It is used for desalination of sea water. 2. What do you understand by depression of freezing point? Derive the relationship between depression of freezing point and molar mass of the solute. Answer: The decrease in freezing point when non-volatile solute is added to a solvent, is called depression in freezing point. The pressure exerted by an individual gas in a mixture is known as its 3. State Henry’s law. Why do gases always tend to be less soluble in liquids as the temperature is raised? Answer: Henry’s law states, ‘The partial pressure of the gas dissolved in a liquid is directly proportional to its mole fraction. p gas= K H x gas, where xgas is the mole fraction of gas and pgas is the partial pressure of the gas. When temperature is increased, K H (Henry’s law constant) increases, therefore, the solubility of gases in liquid decreases. 4. State Raoult’s law for the solution containing volatile components. Write two differences between an ideal solution and a non-ideal solution. Answer: Raoul...

Introduction In this chapter, we will discuss about liquid solutions and their formation. This will be followed by studying the properties of solutions, like vapour pressure and colligative properties. We will begin with types of solutions and expressions for concentration of solutions in different units. Thereafter, we will state and explain Henry’s law and Raoult’s law, distinguish between ideal and non-ideal solution and deviation of real solutions from Raoult’s law. We will also discuss abnormal colligative properties alongwith association and dissociation of solute. Types of Solutions All the three states of matter (solid, liquid and gas) may behave either as solvent or solute. When a solution is composed of only two chemical substances, it is termed as binary solution. Depending upon the state of solute or solvent, binary solutions can be classified as Some Important Definitions 1. Mixture When two or more chemically non-reacting substances are mixed, they form mixture. 2. Heterogeneous Mixture It consists of distinct phases, and the observed properties are just the sum of the properties of individual phases. 3. Homogeneous Mixture It consists of a single phase which has properties that may differ from one of the individual components. 4. Solution The homogeneous mixture of two or more components such that at least one component is a liquid is called solution. 5. Solvent It is the constituent of solution which has same physical state as that of solution and generally...
