März 2020 Die Potentiometrie ist eine Form der Titration, bei der du mithilfe einer Spannungsmessung die Konzentration deiner Probelösung bestimmen The titration system is comprised of a central unit controlling an automatic burette and a potentiometer.

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. To do this, two electrodes are used, an indicator electrode (the glass electrode and metal ion indicator electrode) and a reference electrode. 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 Potentiometric titration is a technique similar to direct titration but in this no indicator reagent is used instead an electrode is used as an indicator.
