That's not a stable compound.
If you meant HPO4--, it can be formed by either the reduction of the PO43- ion or oxidation of the H2PO4- ion.
The conjugate base of the H2PO4 ion is the HPO4^2- ion. This is formed when H2PO4 loses a hydrogen ion (H+).
The conjugate base for HPO4^2- is H2PO4^-.
The conjugate base of HPO4 2- is H2PO4 -, which results from the loss of one hydrogen ion (H+) from the dihydrogen phosphate ion.
The pKa values of HPO4 (hydrogen phosphate) are as follows: pKa1 = 2.15, pKa2 = 7.20, and pKa3 = 12.35.
HPO4^2- is an acidic species as it can donate a proton (H+) in solution. NO2, on the other hand, can act as a base by accepting a proton. When mixed together, they can form a reaction where HPO4^2- donates a proton to NO2, leading to the formation of H2PO4^- and NO2^-.
The conjugate base of the H2PO4 ion is the HPO4^2- ion. This is formed when H2PO4 loses a hydrogen ion (H+).
The conjugate base for HPO4^2- is H2PO4^-.
The conjugate base of HPO4^-2 is PO4^-3 because when HPO4^-2 loses a single hydrogen ion in a reaction, it forms PO4^-3.
The conjugate base of HPO4 2- is H2PO4 -, which results from the loss of one hydrogen ion (H+) from the dihydrogen phosphate ion.

hydrogen phosphate
The pH level of HPO4 (dihydrogen phosphate) depends on its concentration in solution. In general, HPO4 tends to be weakly acidic, causing the solution to have a pH below 7. At low concentrations, the pH may be closer to neutral, while at higher concentrations, it will be more acidic.
This compound is iron(III) hydrogenphosphate.
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)
hydrogen phosphate ion.
This compound is iron(III) hydrogenphosphate.
