NaCl(或KCl)-CH3OH-H2O体系的摩尔电导

CHaOH－HzO体系具有非常特殊的性质，同时在工业生产及临床治疗方面有着十分广泛的应用，文献中有大量地从不同角度就这类体系进行研究的报道．然而，就N3CI及KCI－CH30H－H20体系的电导研究而言，文献中仅有关干KCI－CH30H－H20（间隔20％CH30H）的部分研究工作．作为全面、系

Molar Conductances of NaCl and KCl in Aqueous Methanol Mixtures at 298.15K

Molar conductances of NaCl and KCl in 0~100%(ω/ω) CH3OH-H2O have been measured by using the alternating conductance bridge method resembling that of Shedlovsky. The results show that the limiting molar conductances (Λ0) of both NaCl and KCl have the lowest curve points around 55%(ω/ω) CH3OH and the limiting molar conductances (Λ0) of KCl are larger than that of NaCl in 0~100%(ω/ω) CH3OH-H2O mixtures, which can be accounted for in terms of the micro-structure and ionic solvated situation of NaCl and KCl aqueous methanol solution. Furthermore, experimental limiting molar conductances (Λ0) for KCl-CH3OH-H2O system in this work are critically compared with that of Amis, which shows that measured results in this work are more reliable.
