Answer 2

In chemistry, water of crystallization or water of hydration or crystallization water is water that occurs inside crystals. Water is often incorporated in the formation of crystals from aqueous solutions.In some contexts, water of crystallization is the total weight of water in a substance at a given temperature and is mostly present in a definite (stoichiometric) ratio. For egample cuso4.5h20 has 5 water molecules these water molecules are known as water of crystallization
