초록

여러組成의 아세톤-물 및 포름酸-물 중에서 각각 알칼리鹽化物(LiCl, NaCl, KCl, RbCl, CsCl)의 稀薄溶液의 電導度를 $^30{\circ}C$˚에서 측정하였다. 아세톤-물 混合溶媒中에서의 알칼리鹽化物의 電導度의 結果를 Debye-Huckel-Onsager式으로 解析하였고, 溶媒組成에 따르는 極限當量電導度의 변화를 電解質의 選擇的 溶媒化現象으로 설명하였다. 포름酸-물 中에서의 알칼리鹽化物의 稀薄溶液의 電導度는 溶媒自體의 强한 이온雰圍氣때문에 그 변화를 比較解析할 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 $^30{\circ}C$. 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.
