Which of the following sets correctly represents amphiprotic species in an aqueous medium? — Ionic Equilibrium Chemistry Question

💡 Solution & Explanation

Amphiprotic species can both donate and accept a proton ($H^+$). $H_2O, HCO_3^-,$ and $H_2PO_4^-$ fit this. $OH^-$ and $CO_3^{2-}$ cannot donate protons in water.
