Solutions Class 12 NEET Chemistry
According to the CBSE Syllabus 2026-27, this chapter has been renumbered as Chapter 1.
A solution comprises a solute and a solvent. It is defined as a homogeneous mixture of two or more than two substances. They can be classified into three types:
- - Solid solutions
- - Gaseous solutions
- - Liquid solutions
Molarity, mole fraction, percentages, and molality are the terms used to express the concentration of a solution.
Students can refer to the short notes and MCQ questions along with separate solution pdf of this chapter for quick revision from the links below:

Henry’s Law
In liquids, the dissociation of gas is controlled by Henry’s law. The states that the solubility of a gas in a liquid, at a given temperature, is directly proportional to the partial pressure of the gas. Due to the presence of a non-volatile solute, the vapour pressure of the solvent is lowered.
Raoult’s Law
The lowering of the vapour pressure of the solvent is ruled by Raoult’s law. The law states that the relative lowering of the vapour pressure of the solvent over a solution and the mole fraction of a non-volatile solute present in the solution is equal. It is expressed as:
Ptotal= p10x1+p20x2
Ideal Solutions
When a solution obeys Raoult’s law over the entire range of concentrations, it is called an ideal solution. Types of deviations from Raoult’s law:
- Positive deviations
- Negative deviations
