A student mixes \(100.0\text{ mL}\) of \(0.20\text{ M }\text{AgNO}_3\text{(aq)}\) with \(100.0\text{ mL}\) of \(0.15\text{ M }\text{CaCl}_2\text{(aq)}\) at \(25\ ^\circ\text{C}\). A white precipitate of \(\text{AgCl(s)}\) forms immediately. Assuming that \(\text{AgCl}\) has negligible solubility, which of the following correctly ranks the concentrations of the ions remaining in the resulting mixture from greatest to least?

- **A.** \([\text{NO}_3^-] > [\text{Ca}^{2+}] > [\text{Ag}^+] > [\text{Cl}^-]\)
- **B.** \([\text{Cl}^-] > [\text{NO}_3^-] > [\text{Ca}^{2+}] > [\text{Ag}^+]\)
- **C.** \([\text{NO}_3^-] > [\text{Cl}^-] > [\text{Ca}^{2+}] > [\text{Ag}^+]\)
- **D.** \([\text{NO}_3^-] > [\text{Ca}^{2+}] > [\text{Cl}^-] > [\text{Ag}^+]\)
