Question

The oxides which exhibit both acidic and basic characters are said to be ______.

Answer 1

The oxides which exhibit both acidic and basic characters are said to be amphoteric oxides.

Explanation:

Amphoteric oxides are metallic oxides that can behave as both acids and bases, allowing them to neutralise both acidic and basic substances. When they react with an acid or a strong base, they undergo neutralisation to form a salt and water. Common examples include zinc oxide (ZnO) and aluminium oxide (Al₂O₃).
