Disclaimer: Any two of the below mentioned examples of amphoteric oxides can be used to answer this question.
Amphoteric hydroxides are those compounds that can react with both acids and alkalis to produce salt and water. The hydroxides of zinc, aluminium, lead, etc. are amphoteric in nature. Examples of amphoteric hydroxides are Zn(OH)2 (zinc hydroxide), Pb(OH)2 (lead hydroxide) and Al(OH)3 (aluminium hydroxide).
