Why is aluminium oxide called an amphoteric oxide?
Answer and explanation
Correct answer: Because it can react with both acids and bases
An amphoteric oxide shows both acidic and basic chemical behaviour. Aluminium oxide reacts with acids to form aluminium salts and water, while it reacts with strong bases to form soluble aluminate compounds. This ability to react with both kinds of substances gives the name amphoteric. The other choices incorrectly restrict its reactions or describe an impossible physical state.
