The diffusion potential between electrolyte solutions in different solvents: Some quantitative data about the contribution of the transport of solvent molecules through the boundary layer to the diffusion potential

Abstract

Abstract In the diffusion through the boundary layer between electrolyte solutions in different media, the transport of uncharged particles comes into play. The contribution of this transport to the diffusion potential is measured for alkali halide solutions in methanol‐water mixtures. Using Δμ 0 ‐values of individual ions in methanol‐water mixtures, the total diffusion potentials are calculated. It can be concluded that the diffusion potential between electrolyte solutions in different solvents depends mainly on the primary medium effect.
