What do you mean by amphoteric oxides? Give examples along with reaction.

Explanation

The oxides which react with both acids and bases to give salts are called amphoteric oxides.
E.g. aluminium oxide reacts in the following manner with both acids and bases.
`underset("oxide")underset("Aluminium")(Al_2O_3)+ underset("acid")underset("Hydrochloric")(6HCl) rarr underset("chloride")underset("Aluminium")(2AlCl_3)+ underset("Water")(H_2O)`
`Al_2O_3+underset("(base)")underset("Sodium hydroxide")(2NaOH) rarr underset("aluminate")underset("Sodium")(2NaAlO_2)+ underset("Water")(H_2O)`
