Phosphate - Wikipedia

Phosphate - Wikipedia

The phosphate ion is a polyatomic ion with the empirical formula (PO 4) 3− and a molar mass of 94.97 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, H(PO 4) 2−, which is the conjugate base of H
