Station III: Electroplating 1. Calculate the number of coulombs of charge passed through the elec cell Calculate the theoretical number of moles of copper that should have plated out onto the stainless steel 3. Calculate the actual number of moles of copper that plated out. 4. Calculate the percent yield of copper. 5. Suggest the sources of error in your experiment. 6. Write the half-reaction that occur at the anode of the electrolytic cel. Is it oxidation or reduction? 7. Write the half-reaction that occurs at cathode of the electrolytic cell. Is it oxidation or reduction
