چکیده انگلیسی
Electric conductivities of diluted magnesium sulfate solutions in binary mixtures of 1,4-dioxane with water were measured covering a solvent composition range up to 50 wt.% of 1,4-dioxane at temperatures from 5 to 35 °C. Evaluation of the limiting molar conductivity Îâ and the association constant KA is based on the chemical model of electrolyte solutions, including short-range forces. From the temperature dependence of the limiting molar conductivities Eyring's enthalpy of activation of charge transport was estimated. The standard Gibbs energy, enthalpy and entropy of the ion-pairing process were calculated from the temperature dependence of the ion-association constants.
