Expert Answer:

When crystals of certain salts are formed a definite number of molecules of water chemically combined in a definite proportion. Water of crystallization is water that is stoichiometrically bound into a crystal.

Sodium carbonate deca hydrate or washing soda crystals (Na2CO3.10H2O) have 10 water molecules. The 10 water molecules are called water of crystallization.
