There are two reaction equations for phosphate ion and water. They two equations are: i) HPO4 2- + H2O => H3O+ + PO4 3- ii) HPO4 2- + H2O => OH- + H2PO4 -
The conjugate base of the H2PO4 ion is the HPO4^2- ion. This is formed when H2PO4 loses a hydrogen ion (H+).
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)
In this reaction H3O+ is the conjugate acid. The original acid in this reaction is H3PO4
H2PO4- is called dihydrogen phosphate ion. It is the conjugate base of Phosphoric Acid H3PO4 and the conjugate acid of monohydrogen phosphate ion HPO42-Liquid

The chemical formula for dihydrogen phosphate ion is H2PO4-
The conjugate base of the H2PO4 ion is the HPO4^2- ion. This is formed when H2PO4 loses a hydrogen ion (H+).
Hydrogen phosphate or Phosphoric Acid has the formula H3PO4 ; No charge. The Anion, digydrogen phosphate ' H2PO4^(-) has a charge of '-1' The anion, monohydrogenphosphate ' HPO4^(2-) has a charge of '-2'.

When H3PO4 (phosphoric acid) is heated, it undergoes dehydration reactions to form various phosphorus oxides like phosphorus pentoxide (P4O10) and water. Heating can also lead to decomposition of phosphoric acid into phosphorous acid (H3PO3) and water.
Phosphoric acid (H3PO4) dissociates in water to release three hydrogen ions (H+) and one phosphate ion (H2PO4-). This dissociation process occurs in stages, with each hydrogen ion being released successively.
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.
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
