Assertion Zinc is used in the galvanization of iron. Reason Its coating on iron
Assertion Zinc is used in the galvanization of iron. Reason Its coating on iron articles increases their life by protecting them from rusting.
- A. If both Assertion and Reason are correct and Reason is the correct explanation of Assertion
- B. If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion
- C. If Assertion is correct but Reason is incorrect
- D. If Assertion is incorrect but Reason is correct
Step-by-step solution
Zinc is indeed used for galvanizing iron because it protects iron from rusting. The zinc coating acts as a sacrificial anode, corroding preferentially and thus preventing the iron from rusting. Therefore, both the assertion and reason are correct, and the reason correctly explains the assertion.
