Calomel Electrode ( Mercury-Mercurous electrode)- Secondary Reference Electrode

Calomel Electrode 
Standard Hydrogen electrode is a primary reference electrode, the usage is  difficult as it has many disadvantages. Other electrodes with constant electrode potential are called as secondary reference electrodes. Calomel electrode and Silver-Silver chloride electrodes are examples for such reference electrodes.


Calomel electrode cell representation is
Hg | Hg2Cl2 (s) | KCl or Hg , Hg2Cl2 (s) , KCl.  
Calomel electrode acts as an anode or cathode electrode depending on the nature of the other electrode.
