http://snst-hu.lzu.edu.cn/zhangyi/ndata/Debye-H%C3%BCckel_equation.html WebMost extensions to Debye–Hückel theory are empirical in nature. They usually allow the Debye–Hückel equation to be followed at low concentration and add further terms in some power of the ionic strength to fit experimental observations. The main extensions are the Davies equation, Pitzer equations and specific ion interaction theory .
