Which of the following metal oxides is amphoteric in nature?
Correct: C
Amphoteric oxides are metal oxides that exhibit both acidic and basic properties, meaning they react with both acids and bases to form salts and water. Aluminium oxide (Al2O3) is a classic example of an amphoteric oxide. Copper oxide (CuO) and Magnesium oxide (MgO) are basic oxides, while Iron(III) oxide (Fe2O3) is generally considered basic.
