H3PO4, HNO2, H2SO3, HClO, HClO2, HF, H2S, HC2H3O2 etc.) H2O, NO, CO are neutral oxides. Thanks for any help! HSO4- can become H2SO4 or SO4^2-. 14 Is H2SO3 an amphoteric species? . Explanation: An amphoteric substance can act both as an acid in one reaction, and as a base in another reaction. Show activity on this post. Diprotic Acids. So it is an acidic oxide. Ammonium, NH+4 N H 4 + , is NOT AN AMPHIPROTIC species since it can only act as a proton donor to form NH3 N H 3 . Yes, arsenic (III) oxide (As2O3) is amphoteric.
