Question

The process of separation or deposition of crystals from a hot saturated solution on gentle cooling of the solution is called ‘crystallization’. With reference to the statement explain what is meant by ‘water of crystallization. State which physical properties of a crystal are correlated with the water of crystallization.

Answer 1

The water of crystallization is the number of water molecules that combine chemically – in definite proportion with the – concerned salt in the crystalline state.

Or

Some salts, while crystallizing out from their solutions unite with a definite quantity of water, which is known as the water of crystallization. Physical properties are that crystals are solid, definite regular shapes.
