Amphoteric metal oxides react with both acids as well as bases to produce salt and water.

Aluminium oxide is an amphoteric oxide because it reacts with acids as well as bases and form salts and water.

Al2O3     +     6HCl     →     2AlCl3    +    3H2O                      (Basic nature)

Aluminium   Hydrochloric   Aluminium      Water

  oxide            acid          chloride

Al2O3        +       2NaOH    →      2NaAlO2     +     H2O           (Acidic nature)
