A theory providing quantitative results for the conductivity of ions in dilute solutions of strong electrolytes, which enables theKohlrausch equationto be derived. This theory can be stated as: K =A+B?0m, where ?0mis thelimiting molar conductivity.

A=z2eF2/3p?(2/eRT)½,B=qz3eF/24peRT(2/eRT)½
,wherezis the charge of an ion,eis the charge of an electron,Fis Faraday's constant, ? is the viscosity of the liquid,Ris the gas constant,Tis the thermodynamic temperature, andq= 0.586 in the case of a 1,1 electrolyte. The Debye-Hückel-Onsager theory uses the same assumptions and approximations as theDebye-Hückel theoryand is also limited to very dilute solutions (usually less than 10-3M) for which there is good agreement between theory and experiment. The modifications were made by the Norwegian-born US chemist Lars Onsager (1903–76)
