Abstract	전도도법을 이용하여 물과 물-유기용매계에서 몇 가지 이온들의 용매화수를 측정하였다. 용매화된 이온의 Stokes 반지름을 Nightingale 법으로 보정하였으며, 혼합용매계에서의 각 용매의 용매화수는 몇 가지 가정을 세워 산정하였다. 이와 같이 정한 용매화수는 이온의 선택적 용매화를 나타내었고 등용매화점을 이용하여 이온의 선택적 용매화 정도를 알아보았다. The solvation numbers of some ions in water and of KCl in mixed solvent systems were measured using the conductometric method. Stoke's radii of ions in solution were calibrated by the Nightingale method and the solvation numbers of ions in mixed solvents were deduced by simple assumptions. The deduced solvation numbers of each solvent reasonably go with its selective properties of solvation. From the isosolvation point of ions, the selective properties of ionic solvation were discussed.
