Advantages of Conductometric Titrations over Volumetric Titration - QS Study
QS Study

Conductometric titrations have the following advantages over volumetric titration:

The main advantages to the conductometric titration are its applicability to very dilute and colored solutions and to system that involve relative incomplete reactions. For example, which neither a potentiometric, nor indicator method can be used for the neutralization titration of phenol a conductometric endpoint can be successfully applied.

(i) No indicators are required and therefore, colored solution can be conveniently titrated.

(ii) For weak acid and weak base no suitable indicators are available but conductometric titrations can be conveniently carried out.

(iii) More accurate results are obtained by conductometric titrations because the end-point is determined graphically from a number of measurements and not from a single measurement as in volumetric titration.

(iv) Conductometric titration can be accurately carved out for very dilute solutions, where indicator color change is not sharp.

(v) Volumetric titration does not give correct end point for polybasic acids, while conductornetric titration can be conveniently used in such cases.

(vi) Conductometric titration can be used with colored solutions where end point can’t be seen and can be used where there is no suitable indicator.

However, it must be kept in mind that in order to minimize the volume change as little as possible the titre should be about 10 times stronger than the solution to be titrated. Also, the temperature of the solution should be kept constant during titration.
