A hydrated salt is a crystalline salt molecule that is loosely attached to a certain number of water molecules. Salt is created when an acid's anion and a base's cation are combined to produce an acid-base molecule. A salt molecule that is not bound to any water molecules is an anhydrate, and a salt molecule that is bound to water molecules is a hydrated salt. In a hydrated salt, the water molecules are incorporated into the crystalline structure of the salt.
