Vedclass · Answer

(D) According to the Brønsted-Lowry theory,a base is a proton $(H^+)$ acceptor.In the forward reaction: $PO_4^{3-}$ accepts a proton to become $HPO_4^{2-}$,so $PO_4^{3-}$ is a Brønsted base.In the reverse reaction: $C_2O_4^{2-}$ accepts a proton to become $HC_2O_4^-$,so $C_2O_4^{2-}$ is a Brønsted base.Therefore,the two Brønsted bases are $PO_4^{3-}$ and $C_2O_4^{2-}$.

In the following reaction $HC_2O_4^- + PO_4^{3-} \rightleftharpoons HPO_4^{2-} + C_2O_4^{2-}$,which are the two Brønsted bases?
