Answer Details
ZnO is referred to as an amphoteric oxide. This means that it can react as both an acid and a base. ZnO dissolves in both sodium hydroxide solution (a strong base) and mineral acid solution (a strong acid) to give soluble products. When ZnO reacts with sodium hydroxide, it acts as an acid and forms a soluble salt. When it reacts with a mineral acid, it acts as a base and forms a soluble salt. Therefore, ZnO can react with both acids and bases, making it an amphoteric oxide.
