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.
