Yes, it is amphoteric, at the same time it behaves like acid AND like base: it acts as an acid when in a base: ZnO(s) + 2OH-(aq) +H20(l) -> [Zn(OH)4]2-(aq) it reacts as a base when in acid: ZnO(s)...
No, actually it is a amphoteric oxide: Basic nature: ZnO + 2 H+ ----> Zn2+ + H2O Acidic nature: ZnO + 2 OH- + H2O ----> Zn(OH)4-2
reduced?
