Debye–Hückel–Onsager theory

Chemistry

A theory providing quantitative results for the conductivity of ions in dilute solutions of strong electrolytes, which enables the Kohlrausch equation to be derived. This theory can be stated as: K = A + BΛ‎⁰_m, where Λ‎⁰_m is the limiting molar conductivity.
$\begin{array}{l} A = z^{2} e F^{2} / 3 π η (2 / ε R T)^{½}, \\ B = {qz}^{3} e F / 24 π ε R T (2 / ε R T)^{½}, \end{array}$
where z is the charge of an ion, e is the charge of an electron, F is Faraday’s constant, η‎ is the viscosity of the liquid, R is the gas constant, T is the thermodynamic temperature, and q = 0.586 in the case of a 1,1 electrolyte. The Debye–Hückel–Onsager theory uses almost the same assumptions and approximations as the Debye–Hückel theory and is also limited to very dilute solutions (usually less than 10⁻³ M) for which there is good agreement between theory and experiment. The modifications were made by the Norwegian-born US chemist Lars Onsager (1903–76) in 1926–27.
