Abstract:

A constant current microcoulometric method for determining the number of electrons involved in a unit of reaction at a dropping mercury electrode is described in detail. A large capacitor is connected in parallel with the microcell, and a constant current applied to the combination. The results obtained from several tests with both reversible and irreversible reductions are discussed, and the optimum conditions for accurate results with the method are presented. The principal advantage of the amperostatic method over the usual potentiostatic method is the ease with which the number of coulombs passed during the electrolysis can be calculated. Author
