Students in Dr. Jouandot's Physical Science Honors class were able to experience the everyday process of electroplating. Students 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.
Dr. David Jouandot '03 explained, "Students related the moles of electrons transferred to the moles of copper deposited on the key or lost by the electrode. The charge on the copper ion can then be calculated by applying Faraday’s Law. Pre-and post-lab activities helped students relate the non-spontaneous process of electroplating to the Law of Conservation of Matter, oxidation–reduction reactions, anode and cathode, and Faraday’s Law."
Physical Science is showcasing their very own Academic Excellence with this impressive hands-on lab work.
