NCERT Grade 12 Chapter 2, Solutions deals with liquid solutions and their formation followed by studying the properties of the solutions, like vapor pressure and colligative properties. The chapter begins with types of solutions and then various alternatives in which concentrations of a solute can be expressed in a liquid solution. After studying this chapter, students will be able to describe the formation of different types of solutions; express concentration of solution in different units; state and explain Henry’s law and Raoult’s law; distinguish between ideal and non-ideal solutions; explain deviations of real solutions from Raoult’s law; describe colligative properties of solutions and correlate these with molar masses of the solutes and explain abnormal colligative properties exhibited by some solutes in solutions.
Types of Solutions, Expressing Concentration of Solutions, Introduction to Solubility, Solubility of a Solid in a Liquid, Solubility of a Gas in a Liquid, Vapour Pressure of Liquid Solutions, Vapour Pressure of Liquid-Liquid Solutions, Raoult’s Law as a special case of Henry’s Law, Vapour Pressure of Solutions of Solids in Liquids, Ideal and Nonideal Solutions, Ideal Solutions, Non-ideal Solutions, Colligative Properties and Determination of Molar Mass, Relative Lowering of Vapour Pressure, Elevation of Boiling Point, Depression of Freezing Point, Osmosis and Osmotic Pressure, Reverse Osmosis and Water Purification and Abnormal Molar Masses are the topics discussed in this chapter. NCERT Grade 12 Chapter 2, Solutions holds a total weightage of 5 marks in the final examination.
