Potentiometry is the general term given to the method of measuring the electric potential difference between two electrodes connected by an electrolytic solution. The potential of the reference electrode is constant. The other electrode is called the indicator electrode. If this is an ion-selective electrode which is in equilibrium with the solution, the measured electric potential difference is proportional to the (negative) logarithm of the activity of a specific ion in the solution. Examples are the pH glass electrode for measurement of pH, and the TPP+ electrode for measurement of pTPP and calculation of mt-membrane potential.
