Question

Assertion: Zinc is coated on the iron to prevent corrosion in a process called galvanization.

Reason: Zinc is a stronger reducing agent than iron and is more easily oxidized than iron.

• A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion
• B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
• C. Assertion is true but Reason is false
• D. Assertion is false but Reason is true
• E. Both Assertion and Reason are false

Answer 1

The correct option is A Both Assertion and Reason are true and Reason is the correct explanation of Assertion

Coating of iron with zinc to prevent corrosion is called galvanization.
Steel is dipped in a bath of molten zinc. The zinc coated iron is called galvanized iron. Zinc $(E^o=-0.763V)$ is stringer reducing agent than iron $(E^o=-0.44V)$ and is more easily oxidized than iron . Thus during corrosion, Zn is oxidized instead of Fe.
