Question

During electroplating the copper deposited on the negative terminal comes from the electrolyte solution how is the loss of copper from electrolyte solution compensated ?

Answer 1

The loss of Copper ions is compensated by the copper ions released by COPPER ANODE.

Answer 2

The ions from copper gets deposited on the anode.Due to electric current it gets dissolved as solution. Thus the loss of copper from solution gets compensated.
