Chapter 19, Problem 19.22QP

The voltaic cell is represented as

$\text{Zn}(s)|{\text{Zn}}^{2+}(1.0M)||{\text{Cu}}^{2+}(1.0M)|\text{Cu}(s)|$

Which of the following statements is not true of this cell?

1. a The mass of the zinc electrode, Zn(s), decreases as the cell runs.
2. b The copper electrode is the anode.
3. c Electrons flow through the external circuit from the zinc electrode to the copper electrode.
4. d Reduction occurs at the copper electrode as the cell runs.
5. e The concentration of Cu²⁺ decreases as the cell runs.
