Applications of Conductimetry in Non-Aqueous Solutions

Limiting Molar Conductivities of Electrolytes and Individual Ions  

Ionic Association Constants Formation Constants of Triple Ions 

As mentioned in Section 7.1, if we determine the molar conductivity of an electrolyte as a function of its concentration and analyze the data, we can get the value of limiting molar conductivity A°° and quantitative information about ion association and triple-ion formation. If we determine the limiting molar conductivity of an ion (7 °) by one of the methods described in Section 7.2, we can determine the radius of the solvated ion and calculate the solvation number. It is also possible to judge the applicability of Walden s rule to the ion under study. These are the most basic applications of conductimetry in non-aqueous systems and many studies have been carried out on these problems [1-7]. 

Determination of the Solubility Products of Sparingly Soluble Salts 

When a sparingly soluble 1 1 electrolyte, saturated in the solution, is completely dissociated, the relation between the solubility product of the electrolyte (Ksp) and the conductivity of the solution (k) can be expressed, as a first approximation, by
