उत्तर
The metals which can produce amphoteric oxides are aluminium and zinc.
Explanation:
Amphoteric oxides are metal oxides that react with both acids and bases to form salt and water. While elements like sodium, potassium, and calcium form strictly basic oxides, aluminium and zinc can exhibit both acidic and basic behaviours. Their respective oxides (Al2O3 and ZnO) neutralise both strong acids and strong bases.
