What is the difference between potentiometric titration and volumetric titration?

Potentiometric titration and volumetric titration are commonly used titration methods in chemical analysis, but they have fundamental differences in indicating the endpoint. Potentiometric titration relies on measuring potential changes to determine the endpoint of titration. This method does not require accurate measurement of electrode potential values, so the influence of temperature and liquid junction potential is not important, and its accuracy is better than direct potentiometry. In contrast, volumetric titration relies on the color change of the indicator to indicate the endpoint of the titration. This method is more difficult to indicate the endpoint when the solution being tested has color or turbidity, or suitable indicators cannot be found at all. The potentiometric titration method relies on the sudden jump of electrode potential to indicate the endpoint of titration. Before and after the titration reaches the endpoint, the concentration of the analyte in the droplet often changes continuously by multiple orders of magnitude, causing a sudden jump in potential. The content of the analyte is still calculated by the amount of titrant consumed. This difference makes potentiometric titration more accurate and reliable in many cases
