. A Daniel cell contains 0.1 M

\mathrm{ZnS}{\mathrm{O}_4}

solution and 0.01 M

\mathrm{CuS}{\mathrm{O}_4}

solution at its electrodes. EMF of the cell is

View answer and explanation

Correct option: A

1.10 V

Option A (1.10 V) is correct because, under standard conditions (and close enough to it), the EMF of the Daniel cell is approximately the difference between the standard reduction potentials of copper and zinc.
