How can I calculate the molar conductivity of a solution with multiple solutes?
If you are interested in the modelling of electrical conductivity of aqueous solutions containing more than a single salt, then there are already some references in literature, for example for the salinity of natural waters (Limnology and Oceanography Methods, doi 10.4319/lom.2008.6.489) or in systems relevant to chemical engineering (Ind. Eng. Chem. Res., doi 10.1021/ie9605903).
