The auxiliary and reference electrode work in unison to balance out the charge added or removed by the working electrode.
22.
The circuit contains Hg electrode as the ideally polarizable electrode and a reference electrode as the non-polarizable electrode.
23.
This can be done by placing secondary electrodes in each phase and close to interface each phase has a reference electrode.
24.
The literature is filled with discussions about the most appropriate site for the reference electrode to record each of the components.
25.
For practical pH measurement, a second pH independent reference electrode ( such as a silver chloride electrode ) is also used.
26.
A Quasi-Reference Electrode such as a silver / silver chloride wire electrode can be exposed directly to the analyte solution.
27.
When troubleshooting electrode malfunctions, often, most of the problems have to be searched for from the side of the reference electrode.
28.
Therefore, other more stable reference electrodes such as saturated calomel ( SCE ) are commonly used because of their more reliable performance.
29.
After recording, they re-referenced the data to several commonly used reference electrode sites, including the nose and mastoid process.
30.
The potential measurements are performed with the positive terminal of the electrometer connected to working electrode and the negative terminal to the reference electrode.
