Homogeneous mixtures of two or more than two components are called solutions. In the year 1986, Francois Marte a French chemist proposed a law. The law states that the mole fraction of a solute component is proportional to its partial pressure.
Based on Raoult’s law the liquid-liquid solutions are classified into two solutions:
- Ideal solutions are the solutions which obey Raoult’s law
- Non-Ideal solutions are the solutions which do not obey Raoult’s law
The revision notes for chemistry part 1 chapter 2 ‘Solutions’ is available for free.
Frequently asked Questions on CBSE Class 12 Chemistry Notes Chapter 2: Solutions
What are ‘Ideal Solutions’?
The ideal Solutions are those which obey Raoult’s Law at all concentrations and temperatures.
What does the Raoult’s Law state?
Raoult’s Law states that the partial pressure of each component of an ideal mixture of liquids is equal to the vapor pressure of the pure component (liquid/solid) multiplied by its mole fraction in the mixture.
What is a ‘Solute Component’?
The component of the solution which dissolves in the solvent is called solute.
