Amphoteric oxide: Amphoteric oxides are compounds of oxygen which exhibits both acidic as well as basic characteristics. Answer: there is ur answer. Oxides on their own are not acidic or basic, but when added to water, they can react to make acids or bases or even neutral solutions. CO2 + H2O = H2CO3 (carbonic acid) SO3 + H2O = H2SO4 (sulphuric acid) N2O5 + H2O = 2HNO3 (nitric acid) Their acidic nature can also be verified with the pH paper, as the pH values of such acidic solutions would always be much less than 7.
