| 英文摘要 | This paper presents the conductivity measurements for some alkaline earth metal salts MgCl□, MgBr□, Mg(NO□)□, CaCl□, CaBr□ and Ca(NO□)□ by which the ion-solvent interactions are reported in the concentration range in dioxane-water mixtures at mass fraction of 0, 3, 10, 20 and 30% at 30°, 35°, 40℃ and 45 ℃ ±0.01. The conductance data were analyzed for the limiting molar conductivity, A□, by the Fuoss-Edelson conductivity equation for the 2:1 unsymmetrical electrolytes. The results were discussed in terms of the solute-solvent interaction from the temperature coefficient of Walden product, A□η of the electrolyte solutions. Moreover, A□η was found to exhibit a linear relationship with the dielectric constant, ε, of the dioxane-water mixtures. The study gives information regarding the ion-solvent interactions from the mobilities and Walden product of the ions in the solvent. The ions appear to interact appreciably and the ion-solvent interaction tends to increase in the order Ca> Mg for the same anion while for the anions, the trend decreases in the order Cl□ < Br□ < No□. |
