Question

What are amphoteric oxides? Give two examples of amphoteric oxides.

Expert Solution

Step 1

Oxides of metals which have both acidic as well as basic properties are called amphoteric oxides. Such metallic oxides react with acids as well as base to produce salt and water.

If they are made to react with an acidic substance, they acts as a base. If an amphoteric substance is made to react with a base, it acts as an acidic substance. Examples of amphoteric oxides are Al₂O₃ and ZnO.
