When a solution containing lead(II) ions is combined with a solution containing iodide ions, a yellow precipitate is produced. What is the equation for the reaction taking place?
- A$\text{Pb}^+ + \text{I}^- \rightarrow \text{PbI}$
- B$\text{Pb}^+ + 2\text{I}^- \rightarrow \text{PbI}_2$
- C$\text{Pb}^{2+} + \text{I}^- \rightarrow \text{PbI}$
- D$\text{Pb}^{2+} + 2\text{I}^- \rightarrow \text{PbI}_2$
