Electroplating Silver On Copper

Electroplating
In this demonstration, copper is plated onto the surface of a stainless steel object. Copper from the anode is oxidized to Cu 2+ which is reduced at the cathode to form the solid copper plating. The copper sulfate solution serves as an electrolyte solution as well as the source of the Cu 2+ to be plated on the cathode. ... View Document
