उत्तर
Zinc oxide
Explanation:
An amphoteric oxide is a metallic oxide that exhibits both acidic and basic properties, meaning it can react with both acids and bases to form salt and water. Zinc oxide (ZnO) is amphoteric because it reacts with hydrochloric acid to form zinc chloride and also reacts with sodium hydroxide to form sodium zincate.
