Answers
Answer:
The number of water molecules chemically combined in a definite molecular proportion with the salt in its crystalline state is called Water of Crystallization. ... 5H2 O (crystalline copper sulphate also known as blue vitriol ) when heated becomes white powdery CuSO4 (anhydrous copper sulphate).
Answer:
In chemistry, water of crystallization or water of hydration are water molecules that are present inside crystals. 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.

Activity to demonstrate water of crystallization :
Take a few crystals of hydrated copper sulphate in a dry test tube and heat the test tube. We observe water droplets on the walls of the test tube. ... Water of crystallisation is the fixed number of water molecules present in one formula unit of a salt.
