Vedclass · Answer

(A) Galvanised iron is iron coated with a thin layer of zinc. Since zinc has a more negative standard electrode potential $(E^{\circ}_{Zn^{2+}/Zn} = -0.76 \ V)$ compared to iron $(E^{\circ}_{Fe^{2+}/Fe} = -0.44 \ V)$,zinc acts as a sacrificial anode. It undergoes oxidation 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.
