The oxide which shows both acidic and basic nature when reacted with acids and base. Eg Al2O3. Al2O3 + HCl ----> AlCl3 + H2O Al2O3 + NaOH ---->NaAlO2 + H2O In first reaction amphoteric oxide is reacted with acid in which it forms a salt and water. Similarly in second reaction it is reacted with a base in which it forms salt and water.
