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.

Using a Teaching Model to Correct Known Misconceptions in Electrochemistry P. A. Huddle, Margaret Dawn White, and Fiona Rogers
A concrete teaching model for electrochemistry is presented here. It addresses many common student misconceptions about current flow by demonstrating what is occurring at the microscopic level in an electrochemical cell. Both the scope and limitations of the model are discussed.

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.

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.

Electrode Processes and Aspects Relating to Cell EMF, Current, and Cell Components in Operating Electrochemical Cells: Precollege and College Student Interpretation N. A. Ogude and J. D. Bradleu
Four areas that present difficulty among high school pupils and tertiary level students in relation to the processes that take place in operating electrochemical cells were identified, including conduction in the electrolyte, electrical neutrality, electrode processes and terminology, and aspects relating to cell emf, current, and cell components. A 20-item questionnaire was designed to determine how widespread misconceptions in these areas were.
