Alum /ˈæləm/ is both a specific chemical compound and a class of chemical compounds. where A is a monovalent cation such as potassium or ammonium and M is a trivalent metal ion such as aluminium or chromium(III).[1] When the trivalent ion is aluminium, then the alum is named after the monovalent ion.
