In Ion Selective Electrode?

An ion-selective electrode (ISE), also known as a specific ion electrode (SIE), is a transducer (or sensor) that converts the activity of a specific ion dissolved in a solution into an electrical potential. The voltage is theoretically dependent on the logarithm of the ionic activity, according to the Nernst equation.

How does an ion-selective electrode work?

The ion-selective electrode works based on the principle of a galvanic cell. ... The difference in potential between the electrode and the membrane depends on the activity of the specific ion in solution. The strength of the net charge measured is directly proportional to the concentration of the selected ion.

Which electrode is ion-selective electrode?

Ion-selective electrodes (ISEs) are potentiometric sensors that include a selective membrane to minimize matrix interferences. The most common ISE is the pH electrode, which contains a thin glass membrane that responds to the H+ concentration in a solution.
