Is calomel ionic or covalent?
Calomel is mercury(I) chloride (mercurous chloride). It is ionic and contains the Hg22+ ion and the Cl- ion.
What is the advantages of calomel electrode?
It cannot be used above 50 degree because the Hg2Cl2 breaks down,yielding an unstable readings. Mercurous chloride used in calomel electrode is a toxic substance
Why mercury placed at the bottom of calomel electrode?
Mercury is placed at the bottom of a calomel electrode to provide a stable and well-defined interface between the electrode and the electrolyte solution. This helps to maintain a consistent potential at the electrode/solution interface, making it a reliable reference electrode in electrochemical measurements.

Describe the construction of calomel electrode?
It consists of tube in the bottom of which is a layer of mercury ,over which is placed a paste of Hg+HgCl2.The remaining portion of cell is filled with a solution of normal or decinormal or saturated solution of KCl. a platinum wire dipping into the mercury layer is used for making electrical contact. the side tube is used for electrode is formulated as;Hg,Hg2Cl2,KCl. the electrode can be coupled with the hydrogen electrode of unknown pH.
What is a good substitute for a saturated calomel electrode?
For example, the silver/silver chloride electrode (without mercury).
