Abstract
RECENT work on the effect of the solvent on the hydrogen over potential1 has proved a fruitful source of evidence on the relative probability of the various suggested slow stages in the reactions at the cathode during the electrolytic evolution of hydrogen. No corresponding evidence seems to be recorded for the solvent effect on the oxygen overpotential, concerning which the following is a preliminary report. Few media are available for such experiments owing to anodic oxidation : aqueous acetic acid and aqueous dioxane were chosen for their suitable properties in this respect.
