Question

Q10. Why does aluminum not undergoes corrosion but iron does?

Answer 1

Explanation:

Aluminum unlike iron and steel,does not rust or corrode in moist conditions. Its surface is protected by a natural layer of aluminium oxide. This prevents the metal below from coming into contact with air and oxygen.
