# A galvanic cell is constructed at \(298\text{ K}\) using a \(\text{Ni(s)}\) electrode immersed in \(1.0\text{ M }\text{Ni(NO}_3)_2\text{(aq)}\) and a \(\text{Cu(s)}\) electrode immersed in \(1.0\text{ M }\text{Cu(NO}_3)_2\text{(aq)}\). The two half-cells are connected by a salt bridge filled with \(\text{KNO}_3\text{(aq)}\). The standard reduction potentials are shown below.

\[\text{Ni}^{2+}\text{(aq)} + 2\,e^- \rightarrow \text{Ni(s)} \quad E^\circ = -0.25\text{ V}\]
\[\text{Cu}^{2+}\text{(aq)} + 2\,e^- \rightarrow \text{Cu(s)} \quad E^\circ = +0.34\text{ V}\]

Which of the following correctly identifies the electrode that serves as the negative terminal of the cell and describes the direction in which \(\text{NO}_3^-\text{(aq)}\) ions migrate through the salt bridge as the cell operates?

Which of the following correctly identifies the electrode that serves as the negative terminal of the cell and describes the direction in which \(\text{NO}_3^-\text{(aq)}\) ions migrate through the salt bridge as the cell operates?

- **A.** Negative terminal: \(\text{Cu(s)}\) ; Direction of \(\text{NO}_3^-\text{(aq)}\) migration: Toward the \(\text{Ni(s)}\) half-cell
- **B.** Negative terminal: \(\text{Cu(s)}\) ; Direction of \(\text{NO}_3^-\text{(aq)}\) migration: Toward the \(\text{Cu(s)}\) half-cell
- **C.** Negative terminal: \(\text{Ni(s)}\) ; Direction of \(\text{NO}_3^-\text{(aq)}\) migration: Toward the \(\text{Cu(s)}\) half-cell
- **D.** Negative terminal: \(\text{Ni(s)}\) ; Direction of \(\text{NO}_3^-\text{(aq)}\) migration: Toward the \(\text{Ni(s)}\) half-cell
