Vedclass · Answer

(A) Rusting of iron is an electrochemical process. To prevent rusting,iron is connected to a more electropositive metal (like $Zn$ or $Mg$). Since the more electropositive metal acts as an anode and undergoes oxidation,the iron object acts as a cathode and is protected from corrosion. This method is known as cathodic protection.
