WebJan 6, 2024 · However, as concentration increases, the second term becomes increasingly important, so the Davies equation can be used for solutions too concentrated to allow the use of the Debye–Hückel equation. For 1:1 electrolytes the difference between measured values and those calculated with this equation is about 2% of the value for 0.1 M solutions. http://snst-hu.lzu.edu.cn/zhangyi/ndata/Debye-H%C3%BCckel_equation.html WebMar 6, 2024 · Short description: Electrochemical equation.
