Since copper is to be coated on an iron nail. A copper plate is made the positive electrode while the iron nail should be the negative electrode.
The electrolyte used in the process should be a copper salt e.g CuSO4 solution.
As electrolysis progresses, the copper electrode(positive electrode or anode) gradually wears away due to the fact that the copper ions are going into the solution and are being deposited on the iron nail.
