| 摘 要： | 在283~308K温度范围内测定了NaCl在DMF和1,2-丙二醇混合溶剂中的电导率,根据公式求得NaCl的摩尔电导率值,应用Kohlrausch经验规则,使用Origin软件进行线性拟合,作图外推求得NaCl在DMF和1,2-丙二醇混合溶剂中的无限稀释摩尔电导率λ0值,并讨论了NaCl溶液的电导率、摩尔电导率、无限稀释摩尔电导率与温度和浓度的关系。

| Abstract: | The electrical conductivity of NaCl in DMF and 1,2-propanediol at 283K to 308K were determined, based on which, the molar conductivity of NaCl in the mixture solvent was calculated. By using the Kohlrausch formula, and the Origin software, the molar conductivity was plotted against the square root of concentration at different temperature. By extrapolating the curves to zero concentration, the molar conductivities of NaCl at infinite dilution in the mixed solvent at different temperatures were obtained. The relat ionships of the conductivity, molar conductivity, and molar conductivity at infinite dilution of NaCl in DMF and 1,2-propanediol mixture solvent were also discussed. |
