Out of the following oxides, the amphoteric oxide is:
विकल्प
Fe2O3
Al2O3
P2O5
N2O
Advertisements
उत्तर
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.
