Abstract

The densities, viscosities and relative viscosities of solutions of several univalent electrolytes Lithium bromide (LiBr), Sodium bromide (NaBr), Potassium bromide (KBr), Rubidium bromide (RbBr) Cesium bromide (CsBr) and reference salts tetra butyl ammonium tetra phenyl borate (BU4NBPh4), tetra butyl ammonium bromide (BU4NBr) and potassium chloride (KCl) were measured over the entire range of concentration at 25 ºC to 45ºC in pure DMSO, pure water and DMSO- H2O binary mixtures. Data was analysed by Jones-Dole equation to determine ion –ion interactions (the A- coefficients), ion- solvent interaction, (the B- coefficients) for alkali metal bromides in pure DMSO, pure water and DMSO- H2O binary mixtures. The values of A- coefficients were small and almost positive in all the cases. The values of B- coefficients were large and almost positive of all the salts in DMSO and DMSO- H2O mixtures, which showed the structure making abilities of the salts in DMSO- H2O mixtures at all the five temperatures. The values of viscosity B- coefficients were found negative for KBr, RbBr and CsBr in pure water at all the five temperatures, which showed the structure breaking abilities of the salts while the values of viscosity B- coefficients of LiBr and NaBr in water at all the five temperatures were found positive and behave as structure makers.
