Abstract
에탄올-물 혼합용매에서 염화카륨의 전도도를 25∼40℃에서 측정하여 Limiting Equivalent Conductance와 Walden Product를 구하였다.
또한 혼합 용매의 밀도, 점도, 유전상수로부터 용매-용매 및 이온-용매 상호작용을 검토하여 물과 에탄올의 회합으로 물의 구조가 0.1 물분율에서 가장 강화됨을 알았다.
또한 혼합 용매의 밀도, 점도, 유전상수로부터 용매-용매 및 이온-용매 상호작용을 검토하여 물과 에탄올의 회합으로 물의 구조가 0.1 물분율에서 가장 강화됨을 알았다.
The equivalent conductivity of the potassium chloride was measured at various temperatures between 25 and 40℃ in ethanol-water mixed solvent system. Density, viscosity, and dielectric constant data are also reported for the mixed solvent.
Limiting equivalent conductivity and Walden product as a function of solvent composition and temperature are reported. The interactions between solvent-solvent and ion-solvent are discussed.
Maxima of ⋀0η0 are found for the potassium chloride solutions in 0.1 mole fraction of ethanol. It is assumed that the maxima of ⋀0η0 correspond to an association of water and ethanol with higher degree of hydration than the association of viscosity.
