摘要:
The reliability of the concentration cell method for determining cation transference numbers has been tested using solutions of LiCl, NaCl, KCl, NaBr and LiBr in ethylene glycol at 25°C. Concentrations in the range 0.0005 to 0.5 mol dm−3were used. Our transference numbers have been compared with those deduced from previous data on moving boundary and conductivity experiments. Good agreement between both sets of values has been found in most of the solutions, but significant discrepancies appear in the cases of NaBr and LiCl. The mean activity coefficients have been calculated from the EMF data and the transference numbers.
