Best Answer

H3PO4 (aq) + H2O (l) ---> 2H3O+ (aq) + PO4-3 (aq)

donor acid + acceptor base ---> conjugate acid + conjugate base

the answer above is wrong

to form a conjugate, the ion H2PO4 - must lose a hydrogen ion H+

i.e

H2PO4 - -H+ = HPO4 2-

(conjugate base)

Conjugate base is allways ONE proton H+ less than its acid which it is conjugated to.

So H2PO4-(monohydrogen phosphate) is the conjugate base of the acid: H3PO4
