Vedclass · Answer

(A) In galvanization,iron is coated with zinc. Since the standard oxidation potential of zinc is higher than that of iron,zinc acts as a sacrificial anode and protects iron from corrosion.Similarly,when a magnesium bar is connected to an iron pipe,magnesium (which has a higher oxidation potential than iron) acts as a sacrificial anode and undergoes oxidation,thereby protecting the iron pipe from corrosion.This process is known as cathodic protection.

In the galvanizing process,iron is coated with zinc. The resulting chemical protection is most similar to that provided when
