(While copper is very thin, many layers of coppering and sanding can slowly build-up surfaces. The scientific goal of this experiment is to determine the efficiency of copper electroplating on nickel coated steel or brass. In electroplating, the metal dissolved from the anode can be plated onto the cathode. Electroplating is an energy intensive process. The waste treatment processes for copper plating solutions and copper-containing rinse waters are well known and in most cases easy to accomplish. The alkaline cyanide-free copper plating process discussed here is based on pyrophosphate chemistry. A strike is an optional preliminary electroplating step that puts a thin but highly adherent layer on.
