What are the chemical name and chemical formulas of alum?
An alum 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, where X is a monovalent cation such as potassium or ammonium. By itself, "alum" often refers to potassium alum, with the formula KAl(SO 4) 2·12 H 2O. Other alums are … See more Alum found at archaeological sites The western desert of Egypt was a major source of alum substitutes in antiquity. These evaporites were mainly FeAl 2(SO 4) 4·22 H 2O, MgAl 2(SO 4) 4·22 H 2O, NaAl(SO 4) 2·6 H … See more Aluminium-based alums have a number of common chemical properties. They are soluble in water, have a sweetish taste, react as acid by turning blue litmus to red, and crystallize in regular octahedra. In alums each metal ion is surrounded by six water molecules. … See more Many trivalent metals are capable of forming alums.
