Hydrates in Chemistry: Definition, Types, and Uses

WebCrystal Hydrates. crystals containing molecules of water. Many salts, acids, and bases are precipitated from aqueous solutions in the form of crystal hydrates. Many naturally occurring minerals, such as gypsum (CaSC4·2H2 O) and carnallite (MgCl2·KCl·6H2O), are examples of typical crystal hydrates. The water of crystallization can usually be ... Hydrates are inorganic salts "containing water molecules combined in a definite ratio as an integral part of the crystal" that are either bound to a metal center or that have crystallized with the metal complex. Such hydrates are also said to contain water of crystallization or water of hydration.
