On the Electroreduction of Anions

Abstract
The electroreduction of anions is often strongly influenced by the electronic charge on the surface of the metallic electrode, and this influence can be traced to the influence of the charge on the composition of the electrical double layer. Experiments cited by others as tending to disprove this supposition are shown to be in fact compatible with it. Neutral molecules containing coordinated chlorine behave with respect to electroreduction much like anions because the chlorine assists in the adsorption of the molecule, and this adsorption is charge sensitive. In all cases the difference in the mechanism of the electroreduction of anions or of neutral particles with anionic groups at different potentials can be interpreted as determined by differences in the conditions of adsorption of the reacting particles.
