Chemical properties. The phosphate ion has a molar mass of 94.97 gmol, and consists of a central phosphorus atom surrounded by four oxygen atoms in a tetrahedral arrangement. It is the conjugate base of the hydrogen phosphate ion HPO 4 2−, which in turn is the conjugate base of the dihydrogen phosphate ion H 2 PO 4 −, which in turn is the conjugate base of orthophosphoric acid, H
