What is crystallization?
Crystallization is the process in which a pure substance is obtained in the form of a crystal from its solution and is called crystallization.

A crystal is a solid that is made up of particles arranged in a geometric pattern.
The process of forming a crystal from a saturated solution is called cystallization.
How crystal is formed
When we take a saturated solution of compound B in water at 40 degrees Celsius, it is prepared by dissolving 200 gm of compound B in 100 gm of water. What will happen if you gradually cool it to 20 degrees Celsius?
But the solubility of compound B in 100 gm of water is only 150 gm, which means when we cool the solution, the remaining 50 gm of compound B comes out as a pure solid. This solid is formed as crystal.
Uses of Cystallization
This method is used for the separation of two solids in which one of the compounds is present in a small quantity and both are soluble in the same solvent. This method can also be used for purification of solids.
The principle of purification by crystallization is based on the difference in the solubility of a substance at different temperatures.
