A student constructs a concentration cell to model the transfer of copper ions between two recycling streams. Two equal-volume solutions of \(\text{CuSO}_4\text{(aq)}\), initially \(1.0\text{ M}\) and \(0.010\text{ M}\), are connected by a salt bridge. A \(\text{Cu(s)}\) electrode is placed in each solution, and the electrodes are connected through an external circuit. As the cell operates at constant temperature, the student records the following data.

Stage	\(\dfrac{[\text{Cu}^{2+}]_{\text{high}}}{[\text{Cu}^{2+}]_{\text{low}}}\)	\(E_{\text{cell}}\) (V)
Initial	100	0.059
Later	10	0.030
Later	2	0.009
Equilibrium	1	0.000

Which statement best explains why the measured cell potential approaches \(0.000\text{ V}\)?
