Activity Coefficients for NaCl in (#omega#)N,N-Dimethylformamide + (1 - #omega#)Water Mixtures at 25deg C

摘要

Activity coefficients for NaCl in N,N-dimethylformamide + water mixtures ocntaining 5,7.5, 10, 15, 30, and 45 mass % DMF have been determined at 25deg C by emf measurements. a decrease of the activity coefficient for NaCl with the DMF increase in the mixture is observed. The activity coefficients at the concentration 0.10 mol.kg~(-1) have been correlated with those reported in the literature for other DMF compositions.
