Basic principle of PH electrode
The electrodes used in PH measurement are also called galvanic cells. The primary battery is a system whose function is to convert chemical energy into electrical energy. The voltage of this battery is called 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 the specific ion activity; the other half-cell is the reference half-cell, usually called the reference electrode, which is generally connected to the measuring solution and connected to the measuring instrument .
