Abstract
The Onsager-Fuoss-Chen theory of conductance for mixtures has been explored and compared with experimental results for the system HCl−MgCl2−H2O from 5×10−5 to 0.02 mol-kg−1 of water. In the theory, the higher order term O(ka) which involves the ion size parameter has been replaced by a linear term with an empirical constant. The theory including the additional linear term agrees well with the experimental results. The mixture effect on the equivalent conductance is small, but on the individual ionic mobilities is substantial.
