The water of crystallization means having a fixed number of molecules present in one formula of a unit of salt. Crystal salts with water of crystallization are known as hydrates. The other names of water crystallization are crystallization water or water of hydration. The water of crystallization is caused by forming purifed crystals from an aqueous solution. These crystals do not include contaminants. These crystals are easily afffected by the heat. Examples of water of crystallization are proteins with more than 50% of the water of crystallization and copper sulfate pentahydrate with five molecules of water of crystallization.1.
