A student tests whether chloride ions in rinse water will form a precipitate when treated with silver ions. The student mixes equal volumes of \(6.0 \times 10^{-5}\text{ M AgNO}_3\) and \(6.0 \times 10^{-6}\text{ M NaCl}\) at \(25^\circ\text{C}\). The volumes are assumed to be additive.

\(\text{AgCl(s)} \rightleftharpoons \text{Ag}^+\text{(aq)}+\text{Cl}^-\text{(aq)}\qquad K_{sp}=1.8\times10^{-10}\)

Which of the following correctly predicts whether a precipitate forms immediately after the solutions are mixed?
