Limiting ionic partial molar volumes and viscosities of Cs+, Na+, (C4H9)(4)N+, Cl-, Br-, I,(-), and BPh4- in aqueous acetone at 308.15 K
Densities and viscosities of CsX (X = Cl-, Br-, I-) NaBr, (C4H9)(4)NBr, and NaBPh4 in (0, 0.2, 0.4, 0.6, and 0.8) weight fraction (w(1)) acetone + water have been measured over the whole composition range at 308.15 K. From the densities, apparent and limiting partial molar volumes of the electrolytes and ions in their mixtures have been evaluated. The viscosity data have been analyzed with the help of the Jones-Dole equation, and the corresponding viscosity B coefficients have been calculated. The ionic B coefficients have been determined using the reference electrolyte NaBPh4.
