Question

What is amphoteric oxides?​

Answer 1

Answer:

In chemistry, an amphoteric compound is a molecule or ion that can react both as an acid and as a base. Many metals (such as copper, zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. ... Amphoteric oxides include lead oxide and zinc oxide, among many others.

Answer 2

Amphoteric oxides react with both acids and alkalis to form salt and water.

Examples of amphoteric oxides are zinc oxide and aluminum oxide-

• 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)
