Explanation

According to Bronsted Lowry acid-base theory:

  • Conjugate acid is a species formed by the addition of proton to the base. or species . Or those chemical species which accepts protons.
  • Conjugate base is a species formed by the removal one proton from the acid. Or those chemical species which donates the proton.
  • Here proton is \(H^+\)

\(H_2C_2O_4(aq)+HPO_{4}^{2-}(aq)\rightarrow HC_2O_{4}^-(aq) + H_2PO_{4}^-(aq)\)

1) Acid will form conjugate base: \(H_2C_2O_4(aq)\)   forming conjugate base \(H_1C_2O_{4}^-(aq)\)

2) Base will form conjugate acid :\(HPO_{4}^{2-}\) forming conjugate acid \(H_2PO_{4}^{-}(aq)\)
