It is acid AND base together, at the same time (amphoteric).
acid : HPO42- + H2O <---> H3O+ + PO43- pKa = 12.32 (very weak acid)
base: HPO42- + H2O <---> OH- + H2PO4- pKb = 6.79 (rather weak base)

Conjugate base of H2Po4?
H3PO4 (aq) + H2O (l) ---> 2H3O+ (aq) + PO4-3 (aq)donor acid + acceptor base ---> conjugate acid + conjugate basethe answer above is wrongto form a conjugate, the ion H2PO4 - must lose a hydrogen ion H+i.eH2PO4 - -H+ = HPO4 2-(conjugate base)
