Abstract

Undergraduate instruction in electrochemistry is often not as exhaustive as given in spectroscopic or chromatographic techniques. In particular, it is not typical to expose students to experiments highlighting the qualitative aspects of electrochemical methods. We have addressed this opportunity by incorporating into upper-level undergraduate laboratories experiments utilizing modern, computer-controlled electrochemical workstations to probe molecular behavior. To this end, exercises of appropriate difficulty are described for calculating rate constants, surface coverage, and deducing electron-transfer mechanisms. These have been observed to be challenging and stimulating for student investigators.

- A Simple Student Experiment for Teaching Surface Electrochemistry: Adsorption of Polyoxometalate on Graphite Electrodes
  David Martel , Neso Sojic and Alexander Kuhn
  Journal of Chemical Education2002 79 (3), 349
  We describe a very simple experiment that allows one to teach the basics of surface electrochemistry. The spontaneous adsorption of a commercially available polyoxometalate is used to modify the surface of a graphite pencil. The electrochemical properties ...
