Which of the following is not basic in nature
Correct answer: A. Aluminum oxide
- A. Aluminum oxide
- B. Magnesium oxide
- C. Potassium oxide
- D. Sodium oxide
Explanation
Aluminum oxide (Al₂O₃) is amphoteric, meaning it can exhibit both acidic and basic properties depending on the environment. It can react with acids, forming aluminum salts and water, and it can also react with strong bases to form aluminate ions. This dual behavior makes aluminum oxide versatile in various chemical reactions and applications, including catalysts and adsorbents.
