A student constructs a galvanic cell using a zinc electrode immersed in a \(1.0 \text{ M ZnSO}_4\text{(aq)}\) solution and a copper electrode immersed in a \(1.0 \text{ M CuSO}_4\text{(aq)}\) solution. The two half-cells are separated by a porous glass frit that permits ion movement between the solutions, as shown in the diagram. As the reaction \(\text{Zn(s)} + \text{Cu}^{2+}\text{(aq)} \rightarrow \text{Zn}^{2+}\text{(aq)} + \text{Cu(s)}\) proceeds, which of the following correctly describes the migration of ions through the porous glass frit and provides the correct justification?
