文摘
The mean activity coefficient of RbCl or CsCl in N,N-dimethylformamide (DMF) + water mixtures was determined by potentiometric measurements at 298.15 K in the range w = 0.10 to 0.40 DMF. The Pitzer model was adopted to describe the behavior of the electrolytes. We also obtained the osmotic coefficients and the Gibbs energies of transfer of rubidium or cesium chloride from water to DMF + water mixtures.
