Vedclass · Answer

(A) The standard reduction potential of $Zn^{2+}/Zn$ is $-0.76 \ V$,while that of $Fe^{2+}/Fe$ is $-0.44 \ V$.Since zinc has a more negative electrode potential than iron,it acts as a sacrificial anode.Zinc gets oxidized in preference to iron,thereby protecting the iron from rusting.Thus,both the Assertion and the Reason are correct,and the Reason is the correct explanation of the Assertion.

Assertion : Galvanised iron does not rust.
Reason : Zinc has a more negative electrode potential than iron.
