Prediction of the Conductance of Strong Electrolytes and the Calculation of The Ionization Constant of Weak Electrolytes in a Dilute Solution By a New Equation

摘要

In order to predict the conductance for dilute 1-1 valent electrolyte solutions, a new conduc- tance equation was proposed based on the Onsager and Onsagar-Fuoss-Chen conductance equa- tion. It has only one parameter A, which can be obtained directly from the data of ionic limiting molar conductivity Λ~∞_m, and its expression is very simple. The new equation has been verified by the experimental molar conductivities of some single strong electrolyte and mixed electrolyte solu- tions at 298.15 K reported in literatures.
