What Is Electroplating and How Does It

2018125ensp;0183;ensp;A simple example of the electroplating process is the electroplating of copper in which the metal to be plated (copper) is used as the anode and the electrolyte solution contains the ion of the metal to be plated (Cu 2+ in this example). Copper goes into solution at the anode as it is plated at the cathode.
