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.

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.

Students' Misconceptions in Electrochemistry Regarding Current Flow in Electrolyte Solutions and the Salt Bridge Michael J. Sanger and Thomas J. Greenbowe
Several researchers have documented students' misconceptions in electrochemistry. One reason for the interest in studying electrochemistry is that surveys of students and teachers suggest that students find this topic difficult and research confirms that students' beliefs about problem complexity affect their performance and learning.

Redox reactions and the electropotential axis Vella, Alfred J.
An introductory discussion should not get bogged down with the problems of representing cells by standard cell diagrams and notations and instead should concentrate on the chemistry of galvanic cells and the use of these cells in describing the concepts of redox chemistry.

Chemical queries. Especially for introductory chemistry teachers Young, J. A.; Malik, J. G.; Quagliano, James V.; Danehy, James P.
(1) Why different potential for copper/zinc cells when using nitrates vs. sulfates? Why is neither cell potential as large as predicted by Nerst equation? (2) Do elements in the zinc subgroup belong to the transition series? - answer by Quagliano. (3) How can the 2,4,5-trichloro derivative of phenoxyacetic acid be prepared? - answer by Danehy.
