主 题：Electrolyte Prediction Conductance equation Constant of ionization
摘 要：In order to predict the conductance for dilute 1 1 valent electrolyte solutions, a new conductance equation was proposed based on the Onsager and Onsagar Fuoss Chen conductance equation. 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 solutions at 298.15 K reported in literatures. The results are in good agreement with the experimental data. Meanwhile the ionization constants of some weak electrolyte solutions were calculated by a modified equation of this new equation, and it was also found that the calculation results are in good agreement with the data in the literature.
