| 摘 要： | 在298.15k和常压下,测定了NaCl和KCl溶于不同比例的DMSO和水混合溶剂中的溶液密度。计算了两种盐在相应混合溶剂中的表观摩尔体积φ_v。利用外推法得到了盐在无限稀释时的偏摩尔体积φ_v°,考查了φ_v°随混合溶剂中DMSO的摩尔分数的变化关系,对结果进行了定性讨论。

| Abstract: | Densities of solutions containing DMSO.H_2O and salt were measued at 298.15K and atmosphere pressure.Apparent mohtr volumes of salts in the binary mixtures of DMSO+H_2O were caculated,partial molar volumes of salts in infinite dilution were esti-mated by extrapolation from the results of experiment.The relationshop between the par-tial molar volumes of salts and the molar fraction of DMSO in mixed solvents has been found.The results was qualitatively discussed in brief. |
