Question

calomel electrode is an example of

Answer 1

The Saturated calomel electrode (SCE) is a reference electrode based on the reaction between elemental mercury and mercury(I) chloride. ... The electrode is normally linked via a porous frit to the solution in which the other electrode is immersed. This porous frit is a salt bridge.

Answer 2

Calomel electrode is an example of a reversible system.

• To use as a reference electrode, we use the calomel electrode and it is established on a reaction between the chloride solution of mercury and mercury.

• The structure of the calomel electrode is that at the bottom this electrode is shaped with a frit and the electrode is made of an outer glass tube.
• The calomel is considered the secondary electrode as the calomel's potential remains the same for a long time.
