Question

During electroplating the copper deposited on the plate connected to negative terminal comes from the solution. How this loss of copper from solution compensated?

Answer 1

Answer:

During electroplating the copper deposited on the plate connected to negative terminal comes from the solution. ... Thus the loss of copper from the solution gets compensated and the process keeps going. This means that copper gets transferred from one plate to another.

Answer 2

It is compensated by connecting copper rod on anode.

Since anode is positively charged and copper breaks into Cu2+ ion in solution and cathode is negatively charged hence Cu2+ move on cathode from solution and new Cu2+ move from anode to Solution. And the process keeps going.

Therefore, we see that Copper rod becomes thin as time passes.

Hope it helps.
