A Study on the Activity Coefficient of Electrolyte in the Mixed Solvents

Zhang Suojiang, Wu Zhisheng (Dep. of Ckem. Henan Univ. )  

This paper based on the view point of non-prefer solvation and from the theory of the total Gibbs free energy G is always constant in a fixed quantity of solution,no matter whether solvated or not , get a activity coefficient formula:We use the formula correlated the exprimental data, the results show that it is approximately suited when the electrolyte concentration I0.1N.
