Direction for: In each of the following questions a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements mark the correct answer as
Assertion: Galvanised iron does not rust. Reason: Zinc has a more negative electrode potential than iron.A) If both Assertion and Reason are true and Reason is the correct explanation of Assertion.
B) If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
C) If Assertion is true but Reason is false.
D) If both Assertion and Reason are false.
Correct Answer: A
Solution :
Galvanised iron i.e., iron coated with zinc does not rust easily as zinc has more negative electrode potential \[(-0.76V)\]than iron. \[(-0.41\text{ }V)\] i.e., zinc is lesser reactive than iron.
