WebAug 21, 2024 · In each case, a halogen higher in the group can oxidize the ions of one lower down. For example, chlorine can oxidize bromide ions to bromine: (3) Cl 2 + 2 Br − → 2 Cl − + Br 2. The bromine forms an orange solution. As shown below, chlorine can also oxidize iodide ions to iodine: (4) Cl 2 + 2 I − → 2 Cl − + I 2. WebIn effect, the electron has been transferred from the iron to the oxygen. This combined redox reaction is possible if there is a surplus of Fe+2 and oxygen simultaneously. The iron serves as the reducing agent, and is itself oxidized. The oxygen serves as the oxidizing agent and is itself reduced.
