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:
