Conductimetry - A Method that is Not Based on Electrode Reactions 

Conductimetry is a method of obtaining analytical and physicochemical information by measuring the conductivities of electrolyte solutions [25]. Conductivity cells have two or four electrodes, but the processes that occur at or near the electrodes are not directly related to the information obtained by conductimetric measurements. 

u is the electric mobility of ion i and the proportionality constant l (= Zj Fwj) is the ionic conductivity or the molar conductivity of ion i. 

If a strong electrolyte, consisting of v+ pieces of cation Bz+ and v pieces of anion Bz, is dissolved to prepare a solution of concentration c, the following relations exist  

The values of A, 2, and 2 decrease with increasing electrolyte concentration, due to the influence of ion-ion interactions. Kohlrausch found the following experimental relation for dilute solutions of strong electrolytes
