What is Crystallisation used for?

1.	What is Crystallisation used for?
Answer» Crystallisation is 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. Crystallisation technique is better than simple evaporation technique as some solids decompose or some, like sugar, may get charred on heating to dryness. some impurities may remain dissolved in the solution even after filtration. On evaporation these contaminate the solid.
