Unlike dry cells, the mercury cell has a constant cell potential throughout its useful life. Why?

Options

  1. AThe mercury cell uses a solid electrolyte, which maintains constant ionic conductivity.
  2. BThe mercury cell has a high initial voltage, which remains unchanged over time.
  3. CBecause Ions are not involved in the overall cell reaction of mercury cells.
  4. DThe mercury cell contains a constant supply of mercury, ensuring a consistent potential.

Correct answer

C. Because Ions are not involved in the overall cell reaction of mercury cells.

Step-by-step solution

Correct Option is : (C) Because Ions are not involved in the overall cell reaction of mercury cells.
