Question

Rinoy wants to electroplate copper on an iron nail.

What should he use as the positive electrode and negativ
electrode for this process?

Which electrolyte should he use for the process?

Which of the two electrodes will gradually wear away
during electrolysis-anode or cathode?​

Answer 1

The answers of the given questions are as follows -

• In this case, the copper metal will be anode and the iron nail will be cathode.
• Here, the copper sulfate or CuSO4 solution will be used as the electrolyte.
• In this process, the copper anode will gradually wear away during the electrolysis process to create the copper electroplating layer on the surface of the iron nail at the cathode.
