Ion-Solvent and Solvent-Solvent Interactions. X-ray Study of Aqueous Alkali Chloride Solutions
The first neighbour model, FNM, used frequently for the description of hydration has been modified by dropping the assumption that the structure of the "free" solvent is identical with that of the pure solvent. The modified model, FNM2, reproduces the experimental X-ray structure functions of alkali chloride solutions quite well and enables the study of perturbed solventsolvent interactions. Th...

Ion segregation in aqueous solutions.
Microscopic structures and dynamics of aqueous salt solutions were investigated with the ultrafast vibrational energy exchange method and anisotropy measurements. In KSCN aqueous solutions of various concentrations, the rotational time constants of SCN(-) anions are proportional to the viscosities of the solutions. However, the reorientation dynamics of the water molecules are only slightly aff...
متن کاملThermodynamics of Ion Association in the Saturated Solution of The Mixed Solvent (methanol+water) and Ion Pairing at 25.0°C
In this study, the ion association phenomenon in the saturated solution of KCl in the mixed solvent(methanol+water) was studied. The solubility of this compound in the mixed solvent (methanol+water by value percent of methanol = 60%), and in the presence of various molarities of NaNO3 wasdetermined by the solvent evaporation method at 25.0°C. The results enable us to estimate the valueof thermo...
متن کاملThermodynamic study of ion- association in KNO3 solution in the mixed solvent (water +methanol)
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...
