Write equation to show the amphiprotic behavior of H2po4-

Answer 1

H2PO4- + H2O <=> H3O+ + HPO4-2

In this equation, H2PO4- acts as an amphiprotic species because it can both donate and accept a proton (H+). In the forward reaction, it donates a proton to water (H2O) to form hydronium (H3O+). In the reverse reaction, it can accept a proton from water to form hydrogen phosphate (HPO4-2).
