30. A Daniell cell initially has 1.0 M and 1.0 M . If sufficient aqueous is added exclusively to the cathode compartment, how will the operating cell potential be affected?

Question

30. A Daniell cell initially has 1.0 M $Zn^{2+}$ and 1.0 M $Cu^{2+}$. If sufficient aqueous $NH_3$ is added exclusively to the cathode compartment, how will the operating cell potential be affected?

Correct answer: B. Adding to the compartment forms the stable complex , drastically reducing the concentration of free (the reactant). A lower reactant concentration decreases the overall cell potential .
