The phosphate ion is a polyatomic ion with the empirical formula PO 3− 4 and a molar mass of g/mol. It consists of one central phosphorus atom surrounded by four oxygen atoms in a tetrahedral arrangement. The phosphate ion carries a −3 formal charge and is the conjugate base of the hydrogen phosphate ion, HPO 2− 4, which is the conjugate base of H 2 PO −
