Basic Principles of PH Electrodes
The electrodes used in pH measurement are also known as galvanic cells. A galvanic cell is a system that converts chemical energy into electrical energy. The voltage of this battery is called the electromotive force (EMF). This electromotive force (EMF) consists of two half-cells. One of the half-cells is called the measuring cell, and its potential is related to a specific ionic activity; the other half-cell is the reference half-cell, usually called the reference electrode, which is generally connected to the measuring solution and is connected to the measuring instrument.
