高浓度非缔合电解质溶液（1：1为1.2 mol dm− 3，M（II）Cl 2型为1.1 mol dm − 3）的相对电导率Λ/Λ 0与相对流动性φ/φ 0之间存在良好的线性关系，其中Λ和φ分别为等效电导率和流动性，上标0表示无限稀释时的值。某些非缔合电解质溶液中氯离子的离子迁移率也满足类似的相关性。这些相关性表明，非特异性离子-离子相互作用对离子迁移率的影响将接近饱和，随着电解质浓度的增加，在这样的浓溶液中的离子迁移率将主要由流体动力学粘性效应决定。在高浓度和不同温度下，不同的电解质溶液的电导率方程的有效性进行了检查。
A good linear relationship was observed between the relative conductivity Λ/Λ0and relative fluidity φ/φ0of non-associated electrolyte solutions at high concentrations (⩾ 2 mol dm−3for 1:1 and ⩾ 1 mol dm−3for M(II)Cl2type electrolytes), where Λ and φ are the equivalent conductivity and fluidity, respectively, and superscript0represents the values at infinite dilution. Ionic mobilities of chloride ion in some non-associated electrolyte solutions also satisfied a similar correlation. These correlations suggest that the non-specific ion—ion interaction effect on the ionic mobility will approach saturation with increasing electrolyte concentration and the ionic mobility in such concentrated solutions will be determined mainly by the hydrodynamic viscous effect. The validity of some conductivity equations was examined for different electrolyte solutions at high concentrations and at different temperatures.
