Polybasic acids such as H2SO4 thus form more than one salt; H2SO4, a dibasic acid, forms two sodium salts, NaHSO4 and Na2SO4. H3PO4, a tribasic acid, forms three sodium salts, NaH2PO4, Na2HPO4 and Na3PO4. The number of protons which an acid loses can be determined from its reaction with alkali: HxA(aq) + xNaOH(aq) ( NaxA(aq) + xH2O(l)
