Conductometric techniques:
In conventional conductometric techniques, an ac frequency of 50-1000 cps is used. This procedure can be modified by using high frequencies (frequencies several mega cyclesper seconds) and the methods are called high frequency methods. In these methods the electrodes are not in the intimate contact of the solution but are separated from the solution by the walls of the containing vessel or some other dielectric (insulating) material. The cell as a whole is now a composite of capacitors and resistor. The response of the cell will depend on (i) the frequency employed, (ii) conductance, (iii) capacitance, (iv) dielectric constant, and (v) the cell geometry. The behavior of this type of cell is relatively complex, other than titration curves with singularity at the end point are also obtained.
