Electrochemical Polishing of Silverware: A Demonstration of Voltaic and Galvanic CellsMichelle M. Ivey and Eugene T. Smith Using a battery and a graphite electrode, an electrolytic cell is constructed to generate a layer of tarnish on silverware. Students then determine that the tarnish can be removed by electrochemically converting it back to silver using aluminum foil and baking soda. Ivey, Michelle M.; Smith, Eugene T. J. Chem. Educ.2008, 85, 68.
