The method of dual dynamic voltammetry, i.e. the simultaneous application of dynamic potential programs to the generator and the collector electrodes of a generator-collector system, is a promising new method for studying the mechanisms of electrochemical processes [1-3]. By applying this method to a gold/gold rotating ring-disk electrode (RRDE) it could be shown that the sharp change in the slope of the surface stress vs. potential curve recorded in the oxide reduction region of gold in sulfuric acid solutions  is accompanied by the formation of soluble, electrochemically reducible gold species which can be detected at the ring electrode.
