The process of separation or deposition of crystals from a hot saturated solution on gentle cooling of the solution is called ‘crystallisation’. With reference to the statement explain what is meant by ‘water of crystallisation’. State which physical properties of a crystal are correlated with the water of crystallisation.
Water of crystallisation is the number of water molecules that combine chemically – in definite proportion with the – concerned salt in the crystalline state.
Some salts, while crystallising out from their solutions unite with a definite quantity of water, which is known as water of crystallisation.
Physical properties are that crystals are solid, definite regular shapes.
