Conductometry
INTRODUCTION
Conductometry is the measurement of the electrical conductivity of a solution. The conductance is defined as the current flow through the conductor. In other words, it is defined as the reciprocal of the resistance. The unit for the conductance is Seimens (S) which is the reciprocal of Ohm's (Ω−1). This method is mainly used for the determination of the physico-chemical properties of the compounds.
PRINCIPLE
The main principle involved in this method is that the movement of the ions creates the electrical conductivity. The movement of the ions is mainly depended on the concentration of the ions.

where A+B− is the solution of strong electrolyte; C+D− is the solution of the reagent. ...
