Diagram of a 19th century, battery-powered, electrochemical plating bath for electroplating copper. The objects to be copper plated, A A, are connected to the negative terminal of the power supply, the cathode. The letters B B represent copper pieces connected to the positive terminal, the anode. The electrodes are immersed in the electrolyte consisting of a solution of copper sulphate. The metal passes from the anode into solution in the electrolyte and is then deposited on the cathode.
