उत्तर
Explanation:
To electroplate an iron nail with copper, the iron nail must be made the cathode (negative terminal), a block of pure copper must be made the anode (positive terminal), and the electrolyte must be an aqueous solution of a copper salt like copper(II) sulphate. This setup satisfies all the necessary conditions for electroplating.
