Vedclass · Answer

(C) Amphiprotic species are those that can act as both a Bronsted-Lowry acid (by donating a proton) and a Bronsted-Lowry base (by accepting a proton).$1$. $H_2PO_4^-$: Can accept $H^+$ to form $H_3PO_4$ and donate $H^+$ to form $HPO_4^{2-}$.$2$. $H_2PO_3^-$: Can accept $H^+$ to form $H_3PO_3$ and donate $H^+$ to form $HPO_3^{2-}$.$3$. $H_2O$: Can accept $H^+$ to form $H_3O^+$ and donate $H^+$ to form $OH^-$.Thus,the set $H_2PO_4^-, H_2PO_3^-, H_2O$ consists of amphiprotic species.
