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 [tex]H^+[/tex]

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

1) Acid will form conjugate base: [tex]H_2C_2O_4(aq)[/tex]   forming conjugate base [tex]H_1C_2O_{4}^-(aq)[/tex]

2) Base will form conjugate acid :[tex]HPO_{4}^{2-}[/tex] forming conjugate acid [tex]H_2PO_{4}^{-}(aq)[/tex]
