Question

What is crystallisation? What are the advantages of crystallisation over evaporation.​

Answer 1

Explanation:

Advantages of crystallization over evaporation - - Crystallization doesn't cause charring of substance (which is a problem with evaporation). - Impurities get removed attaining high purity. - Low temperature & lesser energy requirement in crystallization (lot of energy spent in evaporation).

Answer 2

Answer:

Crystallization or crystallisation is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.

The advantages of crystallisation over evaporation because: Solids like sugar get charred on heating to dryness during evaporation. There is no such problem in crystallisation . The soluble impurities do not get removed in the process of evaporation but such impurities get removed in crystallisation.
