The behaviour of membranes in contact with electrolyte solutions has been studied as regards both electrical potential differences between the two sides of the membranes and the movement of dissolved substances as well as solvent (water) through the membrane. This first communication deals with potential measurements on “cellophane” membranes through which KCl and NaCl solutions diffused towards solutions of ten times smaller concentrations of the same salt. The pH was maintained the same on both sides of the membrane. It was found that pH had a great influence on the measured membrane diffusion potential (MP) (table III). The difference Δ between MP and the liquid junction potential (LJP) was the same in KCl and in NaCl experiments. Δ increases with the pH according to a curve (fig. 1) which is very similar to the dissociation curve of a monobasic acid. There is apparently a close correlation between MP (or Δ) and the dissociation of acid groups in the membrane substance.
