Question

Zinc is more electropositive than iron. So it should get corroded faster than iron but it does not happen
because zinc forms a protective layer of_______ on its surface.​

Answer 1

Answer:

Zinc is more electropositive than Iron but it does not get corroded faster and is used to galvanize iron. Reasons: A thin layer prevents the entering of water and oxygen underneath. Zinc is more reactive than iron.

Explanation:

Answer 2

Answer:

Zinc is more easily oxidized than iron because zinc has a lower reduction potential. ... The more active metals (lower reduction potential) are called sacrificial anodes because as they get used up as they corrode (oxidize) at the anode. The metal being protected serves as the cathode, and so does not oxidize (corrode).
