Answer 2

Answer:

Amphoteric metals are the metals whose oxides react with both acid and base to give salt and water.

Chemical Reaction :

(In acid) Al2O3 + 6HCl -> 2AlCl3 + 3H2O

(Aluminium Oxide + Hydrochloric acid ->Aluminium Chloride + Water)

(In base) Al2O3 + 2NaOH -> 2NaAlO2 + H2O

(Aluminium Oxide + Sodium hydroxide

->Sodium Aluminate + Water).
