Bound water, Water of crystallization

H2O

Water in hydrated minerals are classified as follows;

For example, Alum-(K), Carnallite, Hexahydrite, Tamarugite includes coordinated water only, Chalcanthite, Jôkokuite(Jokokuite) and Siderotil includes 4 coordinated water and 1 anion water, Epsomite includes 6 coordinated water and 1 anion water, Alunogen, Halotrichite and Pickeringite includes 6 coordinated water for 2 Al ions respectively and 5 anion water, and Brucite includes structured water.
