In this case, both compounds … WebIn the chlorine and iodide ion case, the reaction would be: Cl 2 + 2I- 2Cl- + I 2. The iodide ions have lost electrons to form iodine molecules. They have been oxidised. The chlorine molecules have gained electrons to form chloride ions. They have been reduced. This is obviously a redox reaction in which chlorine is acting as an oxidising agent.
