The solubility of oxygen in aqueous KOH solutions has been measured by a Van Slyke apparatus and by an adsorption technique developed by Hildebrand. In the range of concentration of KOH between 0 and 12 N, at 25ยฐC, the two methods yielded identical results; at 760 torr oxygen partial pressure, log S
The cathodic reduction of oxygen in concentrated potassium hydroxide (15 wt-% H,O) at 225ยฐC is greatly at%cted by the presence of dissolved nickel. This effect shows up both in concentration and activation polarizations. These observations, together with indication8 for the presence of nickel redox
