A mathematical model of the current oscillations observed in the potentiostatic electrodissolution of a Cu rotating disk electrode is described and analyzed. The model predicts the conditions under which a CuCl film of constant thickness exists on the Cu surface, along with the conditions under which the film thickness and current density will be oscillatory (in some cases periodic) functions of time. The theoretical predictions are in excellent qualitative agreement with experimental results.
