Silver-Silver Chloride Reference Electrode
Concept #1:
The silver-silver chloride electrode (SSCE) is one of the most commonly used reference electrodes and represents one half of typical electrochemical cell.
Saturated Calomel Reference Electrode
Concept #2:
The calomel reference electrode is based on the following redox couple reaction between Hg2Cl2 and Hg.
The electrode’s cell notation can be written as:
