Answer 1

Amphoteric oxides

1. Amphoteric oxides are Oxides that can react with acids as well as with alkalis.
2. Oxides that have both acidic and basic properties are known as amphoteric oxides.
3. When they react with an acid, they produce salt and water, indicating that they have basic characteristics.
4. They produce salt and water when they react with a base, demonstrating acidic characteristics.

The two examples of amphoteric oxides are:

1. Zinc oxide ($\mathbf{ZnO}$)
2. Aluminium oxide (${\mathbf{Al}}_{\mathbf{2}}{\mathbf{O}}_{\mathbf{3}}$).
