Ion-Solvent Interactions of Some Halides of Common Cations with Organic Solvent Mixtures by Conductometric, Volumetric, Viscometric, and Refractometric Techniques
Electrolytic conductivities, densities, viscosities, and refractive indices of some lithium halides (LiCl, LiBr, and Lil) have been Studied in mass fraction (0.10, 0.20, and 0.30) of ethylene glycol monomethyl ether + methyl alcohol mixtures at 303.15 K. The limiting molar conductivities (A(0)), association constants (K(A)) and the distance of closest approach of file ion (R) have been evaluated using the Fuoss conductance equation (1978). The Walden product is obtained and discussed. The limiting apparent molar volumes (phi(o)(v)), experimental slopes (S(v)*) derived from the Masson equation, and viscosity A and B coefficients using the Jones-Dole equation have been interpreted in terms of ion-ion and ion-solvent interactions, respectively.
