本文从溶质分子在水中溶解时会发生水合作用的观点出发,重新审视了四种小分子羧酸在水溶液中的电导数据,解释了其离子迁移速率随羧酸溶液浓度的变化规律,并提出了一种简便方法来计算羧酸离子在水溶液中的离子水合数。

关键词: 羧酸, 电导, 离子迁移速率, 离子水合数

From the viewpoint of the effect of hydration, the mobility data of four carboxylic acids in aqueous solutions were reviewed, and the concentration dependence of their total mobility had been explained. A new and simple method had been provided to calculate the number of the hydration.

Key words: Carboxylic acids, Conductivity, Mobility, Hydration number
