CONDUCTANCE OF SOME ALKALI HALIDES IN WATER GLYCEROL MIXTURE AT 25 C

Abstract

The electrical conductance of sodium chloride in glycerol-water mixture has been measured at 25 C to test the validity of the Fuoss-Onsager theory in the case of a mixture with viscosity varying in a very large range. With the mixture used as a solvent, it is possible to vary the viscosity by a factor of a thousand. For all the mixtures the concentration method has been used. For the solution in pure glycerol the dilution method has been used due to the high viscosity. The results show that the sodium chloride is not associated up to the lowest dielectric constant corresponding to the pure glycerol. This evidence results from the plots of qy versus c which are linear for all the mixtures. The results have also permitted the analysis of the coefficient of the conductance equation in function of the viscosity of the medium. These coefficients, in the limit of the validity of the Walden rule, should depend only on the dielectric constant and not on the viscosity. In effect the results have con firmed this dependence.
