Question

what is water crystallisation? explain how it can be removed in compounds with an example?​

Answer 1

Water of crystallization is the fixed number of water molecules present in one formula unit of a salt. ... For example, chemical formula of hydrated copper sulphate is CuSO4 · 5H2O. Copper sulphate has 5 molecules of water of crystallisation.

Answer 2

Explanation:

Water is often incorporated in the formation of crystals from aqueous solutions. ... Water of crystallization can generally be removed by heating a sample but the crystalline properties are often lost. For example, in the case of sodium chloride, the dihydrate is unstable at room temperature
