STUDIES ON THE DIFFUSION EFFECT UPON IONIC DISTRIBUTION : II. EXPERIMENTS ON IONIC ACCUMULATION.
The aim of this paper is to present confirmation of the theory of the diffusion effect. By diffusion effect is understood a redistribution of the ions in a system where a continuous diffusion of one electrolyte is going on, which results in a steady state showing accumulation and impoverishment of certain ions. Some typical experiments are recorded and discussed. The results are found in satisfactory agreement with the theory: this can be demonstrated in several ways. The importance of considering activity changes is pointed out. Water migration and the diffusion membrane probably have no appreciable influence upon the diffusion effect under the conditions of these experiments. The diffusion effect may have biological analogies.
