Electroplating with Copper Experiment

Today, Dr. Jouandot's class conducted an electrifying experiment involving electroplating with copper. Our Crusaders applied a thin decorative and protective layer of copper onto a metal key, then investigated the mass changes that occurred as the two electrodes—the key and the copper electrode—were hooked up to a power supply and ammeter. They then related the moles of electrons transferred to the moles of copper deposited on the key or lost by the electrode. Done properly, copper plating began to form across the outside of the key. Through this exciting experiment, our Crusaders learned the value of testing and experimentation as well as the science behind metal plating.
