In H2O the conjugate base is H2PO4-, being conjugated to the acid H3PO4. As well: H3PO4 is conjugated acid to the base H2PO4-.
There are two (or actually even three) possibillities: (answer layout: acid + base --> )H3O+ + HPO4- + Na+ --> H2PO4- + Na+ + H2OH3PO4 + OH- + Na+ --> H2PO4- + Na+ + H2O or even the third:2H3O+ + PO43- + Na+ --> H2PO4- + Na+ + 2H2O
The dihydrogen phosphate ion - (H2PO4)-is an anion.
its an acid, H2PO4- is called dihydrogen phosphate ion. It is the conjugate base of Phosphoric Acid H3PO4 and the conjugate acid of monohydrogen phosphate ion HPO42
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)

There are three protolysis steps:H3PO4 ---> H+ + H2PO4-H2PO4- ---> H+ + HPO42-HPO42- ---> H+ + PO43-
KH2PO4 is made up of potassium dihydrogen phosphate. Some examples of weak acids are water and carbon dioxide, ethanic acid and ammonia.
