A halogen, X, is added to separate solutions of potassium chloride and potassium bromide. The results are shown in the table.
| Solution | Result |
|---|---|
| Potassium chloride | No reaction |
| Potassium bromide | Reaction |
X is then added to potassium iodide solution.
Use the results to predict the ionic equation for the reaction of X with potassium iodide solution.
