Answer: Crystallisationis a process that separates a pure solid in the form of its crystals from a solution. The crystallisation method is used to purify solids.
For example, the salt we get from sea water can have many impurities in it. To remove these impurities, the process of crystallisation is used.
Applications of crystallisation
• Purification of salt that we get from sea water.
• Separation of crystals of alum (phitkari) from impure samples.
