Vedclass · Answer

(C) The concept of conjugate acid-base pairs was proposed by the $Lowry-Bronsted$ theory.According to this theory,an acid is a proton $(H^+)$ donor,and a base is a proton $(H^+)$ acceptor.To find the conjugate base of a species,we remove one proton $(H^+)$ from it.For the given species $H_2PO_4^-$,the removal of one proton $(H^+)$ is represented as:$H_2PO_4^- \rightarrow HPO_4^{2-} + H^+$Thus,the conjugate base of $H_2PO_4^-$ is $HPO_4^{2-}$.

The conjugate base of $H_2PO_4^-$ is
