摘要
The molar and single-ion conductivities of dilute solutions of sodium chloride (C < 0.01 mol-dm(-3)) in binary mixtures of 1,4-dioxane with water were measured covering a broad solvent composition range at temperatures from 5 to 35 degrees C. Accurate viscosity and permittivity data were determined for the organic solvent system. Evaluation of the limiting molar conductivity Lambda(infinity), ionic conductivities lambda(+)(infinity), and lambda(-)(infinity), and the association constant K-A is based on the chemical model of electrolyte solutions, including short-range forces.
