It is a useful means of characterizing an acid. No indicator is used; instead the potential is measured across the analyte, typically an electrolyte solution. Potentiometric Titration TITRIMETRY | Potentiometry☆.

Because no current—or only a negligible current—flows through the electrochemical cell, its composition remains unchanged. For this reason, potentiometry is a useful quantitative method. A potentiometric titration involves the measurement of the volume of the titrant and the pH of the solution. This type of titration can provide more accurate data than a titration that involves a chemical indicator.

In titration. Potentiometric titrations involve the measurement of the potential difference between two electrodes of a cell; conductometric titrations, the electrical conductance or resistance; amperometric titrations, the electric current passing during the course of the titration; and coulometric titrations, the total quantity of electricity passed during the

○ Med ny mikroprocessorteknik kan mätaren visa relevanta  Potentiometrisk titrering - Potentiometric titration. Från Wikipedia, den fria encyklopedin. Mätningar, första och andra derivat i en potentiometrisk titrering. Potentiometric titration is a laboratory method to determine the concentration of a given analyte. It is used in the characterization of acids. In this method, there is no use of a chemical indicator. Instead, the electric potential across the substance is measured.
