Question

what is amphoteric oxide give one example with its reaction

Answer 1

Give two examples of amphoteric oxides. Answer: Oxides of metals which have both acidic as well as basic behaviour are known as amphoteric oxides. Such metallic oxides react with acids as well as base to produce salt and water. Examples of Amphoteric oxides are aluminium oxide and zinc oxide

Answer 2

Amphoteric oxide are those oxides which can react with both acid as well as base to produce salt and water. E.g. Aluminium (Al).

Al2O3 + HCL --> ALCL3 + H2O

Al2O3 + NaOH -->NaAlO2 + H2O
