WebAqueous solutions of iodide salts dissolve iodine better than pure water. This effect is due to the formation of the triiodide ion, which is brown: I − + I 2 ⇌ I − 3 Redox, including … WebIodine reacts also with iodide ions, because the latter can act as Lewis bases, and for this reason the solubility of iodine in water is greatly enhanced in the presence of an iodide. When cesium iodide is added, crystalline cesium triiodide may be isolated from the reddish brown aqueous solution.

Web19 dec. 2024 · You need an IX2 molecule on the right hand side, which would need two iodide ions on the left hand side: 2IX − IX2 + 2eX −. To accept two electrons, we would need two FeX3 + ions: 2FeX3 + + 2eX − 2FeX2 +. Now we have a balanced reaction. All the electrons donated by iodine are accepted by iron. Adding up the two reactions and …
WebSilver salts react with iodine to precipitate silver iodide and generate a reactive electrophilic iodine.
