Coating of silver on iron ring is electroplating
Explanation:
Deposition of a thin film of metal like gold , silver , chromium , nickel on another metallic article with the help of electricity is referred to as electroplating.
The energy change happening here is the conversion of electric energy to chemical energy.
In the process of electroplating the electrons are removed from one of the metals and in this case Ag^+Ag

ions are formed. The process is referred to as oxidation which occurs at the anode. The metal attains a charge and dissolves in the electrolyte. Reduction occurs at the cathode as the metal turns into a neutral atom and attaches to the metal surface.
