Question

give 5 example of Amphoteric oxides fast ​

Answer 1

Answer:

Alkaline solutions contain hydroxide ions. Thus aluminium oxide (Al2O3) reacts with hydrochloric acid to form aluminium chloride and water. With sodium hydroxide solution it forms sodium aluminate (NaAlO2) and water. Other common examples of amphoteric oxides include ZnO, SnO and PbO.

Answer 2

Answer:

Examples of amphoteric oxides are zinc oxide and aluminium oxide.

Explanation:

ZnO(s) + 2HCl(aq) → ZnCl2(aq) + H2O(l)

ZnO(s) + 2NaOH(a) → Na2ZnO2(aq) + H2O(l)

Al2O3(s) + 6HCl(aq) → 2AlCl3(aq) + 3H2O(l)

Al2O3(s) + 2NaOH(aq) → 2NaAlO2(aq) + H2O(l)
