Bromine can displace iodine from iodide ions.
Which equation represents this reaction?
Br+I−→Br−+I\text{Br} + \text{I}^- \rightarrow \text{Br}^- + \text{I}Br+I−→Br−+I
Br−+I2→2I−+Br2\text{Br}^- + \text{I}_2 \rightarrow 2\text{I}^- + \text{Br}_2Br−+I2→2I−+Br2
Br2+2I−→2Br−+I2\text{Br}_2 + 2\text{I}^- \rightarrow 2\text{Br}^- + \text{I}_2Br2+2I−→2Br−+I2
Br2+I−→2Br−+I\text{Br}_2 + \text{I}^- \rightarrow 2\text{Br}^- + \text{I}Br2+I−→2Br−+I
