Chlorine gas is passed through aqueous potassium iodide. What is the ionic equation for the reaction that occurs?
- A$\text{Cl} + \text{I}^- \rightarrow \text{Cl}^- + \text{I}$
- B$\text{Cl}_2 + 2\text{I}^- \rightarrow \text{Cl}_2^- + \text{I}_2$
- C$\text{Cl}_2 + 2\text{I}^- \rightarrow 2\text{Cl}^- + \text{I}_2$
- D$\text{Cl}_2 + 2\text{I}^- \rightarrow 2\text{Cl}^- + 2\text{I}$
