Which of the following substances is an example of an amphoteric oxide?

A. Sodium oxide
B. Carbon dioxide
C. Aluminum oxide✓ Correct Answer
D. Sulfur dioxide

💡 Solution & Explanation

Aluminum oxide exhibits amphoteric properties, enabling it to react with both acidic and basic compounds to yield corresponding salts and water molecules. Oxides such as sodium oxide are strongly basic, whereas carbon dioxide and sulfur dioxide behave as acidic oxides. Identifying oxide types is a frequently tested concept in general science chemistry sections.
