Which of the following ionic or neutral species possess amphoteric properties, enabling them to func — GOC and Organic Chemistry Basics Chemistry Question

💡 Solution & Explanation

Water can act as an acid (forming $OH^-$) or base (forming $H_3O^+$). Bisulfate ($HSO_4^-$) can form $SO_4^{2-}$ or $H_2SO_4$. Bicarbonate ($HCO_3^-$) can form $CO_3^{2-}$ or $H_2CO_3$. Ammonia ($NH_3$) can form the amide ion ($NH_2^-$) acting as an acid, or the ammonium ion ($NH_4^+$) acting as a base. All exhibit amphoteric behavior.
