Cells with Interfaces of Immiscible Electrolyte Solutions

XL VOLTAIC CELLS WITH INTERFACES OF IMMISCIBLE ELECTROLYTE SOLUTIONS 

The Volta potential at the water/nonaqueous solvent boundary, A /, may be measured as the difference in the compensating voltages of the following cells  

The reliability of the experimental A / MX) values was checked for systems containing nitrobenzene, nitromethane, and 1,2-dichlo-roethane as organic solvent by comparing the differences in these values for various pairs of salts with the differences in the Galvani (i.e.,distribution) potemtials, A cp MX) for the same pairs. The differences should be the same. The A cp or Afip data can be used to estimate ion solvation energies in a water-saturated solvent.  

The liquid-liquid patition systems discussed above are in fact very similar to various membrane-type interfaces and may serve as a model for them.A good example is, for instance, the distribution of a dissociated salt between an aqueous solution and a permeable organic polmer.  

The possibility of measuring a nonequilibrium liquid junction (diffusion) potential by using voltaic cells has been checked also
