Question

Rinoy wants to electroplate copper on an iron nail.
0 What should he use as the positive electrode and negative
electrode for this process?
(iWhich electrolyte should he use for the process?
(iii) Which of the two electrodes will gradually wear away
during electrolysis-anode or cathode?​

Answer 2

The answers are as follows:

• Rinoy should use copper at the anode i.e. at the positive electrode while the iron nail at the negative electrode i.e. the cathode.
• A copper sulfate solution must be used as an electrolyte for the process.
• The copper at the anode will wear away during electrolysis, i.e. the anode will wear away during the electrolysis because copper will get accumulated on the iron nail due to which the iron nail will finally br electroplated.
