Question

The electrode with thick rod of impure copper should be attached to the positive terminal of battery because in electroplating process, when electric current is passed through the copper sulphate solution,copper sulphate dissociates into copper and sulphate. The free copper gets drawn to the electrode connected to the negative terminal of the battery and gets deposited on it. An equal amount of copper gets dissolved from the other electrode with thick rod of impure copper, in the solution. Thus,the loss of copper from the solution is restored .As the process keeps going , the copper gets transferred from positive electrode with thick rod of impure copper to the other electrode made up of thin plate of pure copper..

Answer 1

This is an electronic reaction which is great harmful

Answer 2

so is it a question??
