How does E (cell) in a Daniell cell depend on the concentration of Cu2+ and Zn2+ ions?

Options

  1. AE (cell) increases with an increase in the concentration of Cu2+ ions and decrease in Zn2+ ions.
  2. BE (cell) decreases with an increase in the concentration of Cu2+ ions and decrease in Zn2+ ions.
  3. CE (cell) increases with an increase in both Cu2+ and Zn2+ ion concentrations.
  4. DE (cell) decreases with an increase in both Cu2+ and Zn2+ ion concentrations.

Correct answer

A. E (cell) increases with an increase in the concentration of Cu2+ ions and decrease in Zn2+ ions.

Step-by-step solution

The cell potential E (cell) in a Daniell cell increases with an increase in the concentration of Cu2+ ions and a decrease in the concentration of Zn2+ ions.
