This method is a useful way of characterizing an acid. Potentiometric titration uses an indicator electrode instead of an indicator to monitor the endpoint of the titration. Glass and metal ion electrodes are usually indicator electrodes. The potentiometric titration is generally performed using the pH meter as it determines the potential difference between the pH electrode and a reference electrode. Conductometric titration is a laboratory technique of quantitative analysis that is used to identify the concentration of a given solute in a sample mixture.
It is a type of titration in which the reaction mixture's electrolytic conductivity is continuously observed as a reactant is added. The equivalence point is the point at which a sudden change is observed in the conductivity. Advantages of potentiometric titration: The key advantage of using this titration method is that it is an economical method.
It requires a small quantity of substances. The results of this titration are accurate and sharp since the equivalence point is not estimated through a color indicator. Skip to content Natural sciences.

What is potentiometry and its importance? What are the types of potentiometry? In this technique, we can determine the conductivity continuously while adding the reactant. Here, we can obtain the endpoint as a sudden change in the conductivity. Moreover, one major importance of this titration technique is that we can use this method for coloured analytes and suspensions as well, which are difficult to be titrated with normal indicators. When considering the difference between potentiometric and conductometric titrations based on the advantages, the potentiometric titrations do not need an indicator; it is far more accurate, and it can be automated, while the conductometric titrations can be suitable for coloured analytes and suspensions, and give accurate results.
Moreover, based on the disadvantages, the difference between potentiometric and conductometric titrations is that the potentiometric titration is highly pH sensitive while the major disadvantage of conductometric titration is that increased levels of salt can cause errors in the final result.
In summary, the key difference between potentiometric and conductometric titrations is that potentiometric titrations measure the potential across the analyte, whereas conductometric titrations measure the electrolytic conductivity of the analyte.
