WebFor higher concentration the extended Debye Hückel (or Davies) equation can be used: \begin{equation*} \log \left( \gamma_\pm \right) = - \frac{\left z_+ z_-\right A \sqrt{I}}{1 + B \sqrt{I}} + C I … WebDebye-Hückel equation. The Debye-Hückel limiting law, named for its developers Peter Debye and Erich Hückel, provides one way to obtain activity coefficients [1]. Activities, rather than concentrations, are needed in many chemical calculations because solutions that contain ionic solutes do not behave as ideally even at very low concentrations.
