Abstract
여러조성의 아세톤-물 및 포름산-물 중에서 각각 알칼리염화물(LiCl, NaCl, KCl, RbCl, CsCl)의 희박용액의 전도도를 30˚에서 측정하였다. 아세톤-물 혼합용매중에서의 알칼리염화물의 전도도의 효과를 Debye-Huckel-Onsager식으로 해석하였고, 용매조성에 따르는 극한당량전도도의 변화를 전해질의 선택적 용매화현상으로 설명하였다. 포름산-물 중에서의 알칼리염화물의 희박용액의 전도도는 용매자체의 강한 이온분위기 때문에 그 변화를 비교해석할 수가 없었다.

The electric conductances of dilute solutions of alkali chlorides (LiCi, NaCl, KCl, RbCl, CsCl) in a series of acetone-water and formic acid-water mixtures were determined respectively at 30℃. The results of the conductances of alkali chlorides in acetone-water mixtures were analysed by the Debye-Huckel-Onsager equation and the variations of limiting equivalent conductances with the compositions of acetone-water mixtures were explained in terms of selective solvation of electrolytes. The conductances of dilute solutions of alkali chlorides in formic acid-water could not be analysed because of the strong ionic atmosphere of solvent itself.
