Question

Disadvantage of calomel electrode

Answer 1

Answer:

the oxidation potential of the electrode depends on the concentration of KCI,if the concentration of KCI changes the oxidation potential of the electron changes

Answer 2

The solubility of KCl(calomel electrode) is sensitive to temperature variations, which is a key drawback of the SCE.

The disadvantage of calomel electrode :

• When K+ and Cl – ions interfere with the electrochemical operations of the cell, the calomel electrode cannot be utilized to assess cell potentials.
• The electrode's oxidation potential is determined by the KCl content.

• Even though the KCl solution partially evaporates, the concentration of Cl-, and hence the potential of the electrode, stays constant with the SCE.

• The solubility of KCl is sensitive to temperature variations, which is a key drawback of the SCE.
