Metals which form an amphoteric oxide are zinc, tin, lead, aluminium and beryllium. e.g., Zinc and aluminium forms zinc oxide (ZnO) and aluminium oxide (Al₂O₃) respectively.
Amphoteric oxides react with acids as well as bases. Thus ZnO will react with HCl as well as with NaOH.
ZnO+2HCl→ZnCl₂+H₂O
ZnO+2NaOH→Na₂ZnO₂ + H₂O
