Potential of Silver Concentration Cells with Liquids of Low Dielectric Constant

The purpose of this work was to obtain, by means of measurements of electromotive force, information on the behavior and nature of ions present in liquids of low dielectric constant. These measurements were made on silver and silver‐silver chloride concentration cells containing solutions whose dielectric constants were as low as 2.6 and whose specific conductances were as low as ${10}^{\text{−11}}\hspace{0.17em}\mathrm{mho}/\mathrm{cm}.$ The results of these tests were supplemented by conductivity measurements on all the solutions involved. From the data obtained, approximate values for the dissociation constants and electrochemical transference numbers of the electrolytes for various electrolyte‐solvent combinations were deduced.
