Beschreibungen/Notizen

• The bi-ionic membrane potential has been studied on a system consisting of electrolyte solutions separated from another one by an ion exchange membrane. The slope of the linear portion of the curve of potential vs. log activity ratio, log a M a N , was found to be 118 (z M +z N ) mv at 20°C, where a M and z M denote respectively the activity and the charge of permselective ion M present on one side of the membrane and a N and z N, those of the ion N on the other side. This was in good agreement with the theoretical prediction provided that the membrane is permselective to either cations or anions and the relative membrane permeability is a constant.
