Secondary Reference Electrode Consists Of The Following Chemical Formula. Oxygen is reduced consumed at the surface of a noble metal e g platinum or gold cathode the electrode connected to the negative side of the voltage source according to the following chemical reaction. Standard hydrogen electrode she e 0 000 v activity of h 1 molar.
It is used as reference electrode in all potentiometer determinations and to measure ph of the given solution. As discussed below a reference electrode s impedance can strongly affect the performance of a potentiostat. Secondary reference electrodes questions answers 1.

As a secondary reference electrode the ag agcl electrode is the most common due to its simplicity stability and capability of miniaturization. Oxygen is reduced consumed at the surface of a noble metal e g platinum or gold cathode the electrode connected to the negative side of the voltage source according to the following chemical reaction. In electrochemical methods where it is necessary to observe measure or control the potential of another electrode denoted indicator test or working electrode it is necessary to use a reference elec.
