D. There is an increase in the concentration of chloride ions
Answer:D
When the calomel electrode acts as the cathode which of the following does not occur?
A. Mercury ions are discharged at the electrode B. More calomel passes into the solution C. There is a decrease in the concentration of chloride ions D. There is an increase in the concentration of chloride ions
Explanation: When the calomel electrode acts as the cathode. When the calomel electrode acts as the cathode, mercury ions are discharged at the electrode. More calomel passes into the solution. Hence, there is an increase in the concentration of chloride ions.
