WebAug 15, 2024 · As reducing agents, the halide ions follow the trend in reducing strength: (5) I − > Br − > Cl −. Conversely, the halogens follow the opposite order of oxidizing strength: Thus pale green Cl 2 oxidizes Br − to red Br 2 and I − to violet I 2. These colors are better observed if the halogens are extracted into a small amount of hexane.
