Question

Out of the following oxides, the amphoteric oxide is:

Options

• Fe₂O₃

• Al₂O₃

• P₂O₅

• N₂O

Answer 1

Al₂O₃

Explanation:

Aluminium oxide (Al₂O₃) is an amphoteric oxide because it possesses both acidic and basic properties. It reacts chemically with acids (such as hydrochloric acid) to form aluminium chloride and water, and similarly reacts with strong bases (such as sodium hydroxide) to yield sodium aluminate and water. By contrast, Fe₂O₃ is basic, P₂O₅ is acidic, and N₂O is a neutral oxide.
