The solubility of KNO3 in the mixed solvent (water 85%+methanol 15%) were determined by using solvent evaporating method at different temperatures (25, 30, 40, 50, 60 ;C). In addition the equilibrium constant of ion pair formation, KIP, for K+NO3 – ion-pair on the basis of Fuoss contact ion pair model was calculated. Upon choosing the extended Debye-Hückel model for estimating the mean activity...

In the article entitled "A Two-Structure Model for Electrolytic Solutions," by M. H. Lietzke, R. W. Stoughton, and R. M. Fuoss, which appeared in the January 1968 issue of these PROCEEDINGS (vol. 59, pp. 39-45), the following correction, called to our attention by Professor R. P. Mitra (University of Delhi), should be made. The statistical factor of one half was omitted in equation (15); A shou...

The conductance o f N al in acetonitrile-water mixtures was measured at 25.000 ± 0.001 °C for the whole com position range o f the mixed solvent, the salt molarity ranging from 5 • 10“ 5 to 1 • 10-2 . Using the Fuoss-Hsia equation with the Femandez-Prini parameters, the association constants were computed for several values o f the ion-ion distances. The influence o f the mixed solvent composit...

We present a model capturing the important contributors to the effects of temperature on the observable electrophoretic mobilities of small ions, and on solution conductivity and pH. Our temperature model includes relations for temperature-dependent viscosity, ionic strength corrections, degree of ionization (pK), and ion solvation effects on mobility. We incorporate thermophysical data for wat...

the ion-pair association constant values, related to the reaction +  were determined by means of the nmr spectroscopy. the values of the thermodynamic functions of the ion pairing process were calculated on the basis of the nmr results. in addition, the association entropy was found to be dependent on the temperature. comparing the experimental data and the fuoss theory it is found that  ion-pa...

A comprehensive model for calculating the viscosity of aqueous electrolyte solutions has been developed. The model includes a long-range electrostatic interaction term, contributions of individual ions, and a contribution of specific interactions between ions or neutral species. The long-range electrostatic term is obtained from the Onsager-Fuoss theory, whereas the individual ionic contributio...
