General Description
Aluminium sulfate is sometimes referred to as a type of alum. Alums are double sulfate salts with the formula AM(SO 4) 212H 2O where A is a monovalent cation such as potassium or ammonium and M is a trivalent metal ion such as aluminium. The anhydrous form occurs naturally as a rare mineral millosevichite found e.g. in volcanic environments and on burning coal-mining waste dumps. Aluminium sulfate is rarely if ever encountered as the anhydrous salt. It forms a number of different hydrates of which the hexadecahydrate Al2(SO4)316H2O and octadecahydrate Al2(SO4)318H2O are the most common. The heptadecahydrate whose formula can be written as [Al(H2O)6]2(SO4)35H2O occurs naturally as the mineral alunogen.
