NCERT Solutions for Class 12 Chemistry Chapter 2: Solutions – Important Topics

A Solution is a homogeneous mixture of two or more chemically non-reacting substances whose composition can be varied within certain limits. A solution is regarded as a simple phase having more than one component.

Types of Solutions: Based on the states of matter, solutions can be divided into solid solutions, liquid solutions and gaseous solutions.

Solid Solutions: The solvent is in solid state

Liquid Solutions: The solvent is in liquid state

Gaseous Solutions: The solvent is in gaseous state

Solubility: The amount of solute that can dissolve in a solvent to form a solution is called solubility. Solubility depends on factors like temperature, pressure, nature of solvent and solute.

Unsaturated Solution: A solution in which more solute can be added at a given temperature.

Saturated Solution: A solution in which no more solute can be added at a given temperature.

Supersaturated solution: A solution in which more solute than the limited amount is present at a given temperature.

Concentration of Solution: The ratio of the solute to the solvent is known as concentration of a solution

Henry’s Law: Henry’s Law states that the partial pressure (p) of the gas in the vapour phase is proportional to the mole fraction (x) of the gas in the solution. Mathematically,

p = K_H. x

Raoult’s Law: Raoult’s Law states that the Partial vapour pressure of every component in a solution is directly proportional to the mole fraction of that component. Mathematically,

P = P₀X
