Abstract
Abstract
Densities of binary nonaqueous mixtures of acetonitrile (AN) with 2-methoxyethanol (ME), N,N-dimethylacetamide (DMA) and propylene carbonate (PC) were determined over the whole composition range at 298.15 K. The excess molar volumes and the partial molar volumes of both components were calculated from these data. Densities of solutions of NaI, NaBPh4 and Ph4PI in solvent mixtures AN + ME and AN + DMA and of NaI solutions in mixtures of AN + PC were measured over the whole composition range of the mixed solvents at an electrolyte concentration equal 0.05 mol dm−3. From these densities, apparent molar volumes of electrolytes and ions were evaluated and analyzed. The relationship between the apparent molar volumes of ions and (κT
/ε) parameter was tested and discussed.
