The questions consist of two atatements each, printed as Assertion and Reason. While answering these questions you are required to choose any one of the following four responses :
Gavanised iron does not rust .
Zinc has a more negative electrode potential than iron .

A

If both the assertion and reason are true but the reason is ont the correct explanation of assertion

B

If both the assertion and reason are true but the reason is not the correct explanation of assertion.

C

If the assertion is true but reason is false.

D

If assertion is false but reason is rue

Text Solution

Verified by Experts

The correct Answer is:
a
Zinc metal which has a more negative electrode potential tah iron will provide electorns in prefernce of the iron, and therfore corrodes first, Only when all the zinc has been oxidised then the iron start to rust .
