Creator: Chemical Education Material Study.

Complete Record: Describes the construction and operation of an electrochemical cell. Time-lapse photography of the changes at the electrodes and animation of the cell processes show the nature of the electrode reactions, the motion of the electron and ion currents, and the relationship between concentrations and cell voltage. Extreme close-ups of a hydrogen electrode illustrate its operation and lead to a discussion of the table of E⁰ values.
