Electrolysis of several aqueous solutions is carried out using a 9-V battery and pencil leads as electrodes. Because only the electrodes are shown in the videos, it is important to show these still images
or describe how the reactions were performed if students are to make sense of the videos. In each case the anode is on the left and a 9-V battery has been connected to the lead of each of the pencils near the eraser end with an alligator clip.
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.
