Potentiometric titration

Potentiometric titration is a technique similar to direct titration of a redox reaction. No indicator is used; instead the voltage across the analyte, typically an electrolyte solution is measured. To do this, two electrodes are used, a neutral electrode and a standard reference electrode. The voltage is recorded at intervals as the titrant is added. A graph of voltage against volume added can be drawn and the end point of the reaction is half way between the jump in voltage.
