Electrochemical Polishing of Silverware: A Demonstration of Voltaic and Galvanic Cells Michelle 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.

Isolation of Copper from a 5–Cent Coin. An Example of Electrorefining Steven G. Sogo The United States 5cent coin, commonly known as a "nickel", is made of an alloy containing 75% copper and 25% nickel. The experiment is a visually appealing illustration of the process of electrorefining using selective reduction. Sogo, Steven G. J. Chem. Educ. 2004, 81, 530.

Lithium Batteries: A Practical Application of Chemical Principles Richard S. Treptow In recent years batteries have emerged in the marketplace that take advantage of the unique properties of lithium. Lithium metal is an attractive choice to serve as a battery anode because it is easily oxidized and it produces an exceptionally high amount of electrical charge per unit-weight. Treptow, Richard S. J. Chem. Educ. 2003, 80, 1015.

The Household Chemistry of Cleaning Pennies Laurence D. Rosenhein Although it is well known that solutions of vinegar and table salt are effective in removing tarnish from pennies, chemical explanations of this behavior are not included in sources of this "household chemistry" and erroneous explanations have crept into popular literature on this subject; this article provides some relevant empirical information on the system.

An Analysis of College Chemistry Textbooks As Sources of Misconceptions and Errors in Electrochemistry Michael J. Sanger and Thomas J. Greenbowe The oxidation-reduction and electrochemistry chapters of 10 introductory college chemistry textbooks were reviewed for misleading or erroneous statements, using a list of student misconceptions. As a result of this analysis, we provide suggestions for chemistry instructors and textbook authors. Sanger, Michael J.; Greenbowe, Thomas J. J. Chem. Educ. 1999, 76, 853.

The Nernst Equation: Determination of Equilibrium Constants for Complex Ions of Silver Martin L. Thompson and Laura J. Kateley The experiment requires a voltmeter capable of recording millivolts (or a good pH meter) and inexpensive chemicals. It allows students to check the validity of the Nernst equation and compare their experimental Kform values to reported ones. Thompson, Martin L.; Kateley, Laura J. J. Chem. Educ. 1999, 76, 95.
