An alum (/ ˈæləm /) is a type of chemical compound, usually a hydrated double sulfate salt of aluminium with the general formula XAl (SO. 4) 2·12 H. 2O, such that X is a monovalent cation such as potassium or ammonium. [1] By itself, "alum" often refers to potassium alum, with the formula KAl (SO. 4) 2·12 H.
Aluminium chlorohydrate. Aluminium chlorohydrate is a group of water-soluble, [1] specific aluminium salts having the general formula Al n Cl 3n−m(O H)m. It is used in cosmetics as an antiperspirant and as a coagulant in water purification. In water purification, this compound is preferred in some cases because of its high charge, which makes ...
