Reactivity trend of the silver halides

WebAug 21, 2024 · Consider a situation in which one halogen (chlorine, for example) is reacted with the ions of another (iodide, perhaps) from a salt solution. In the chlorine and iodide ion case, the reaction is as follows: (1) Cl 2 + 2 I − → 2 Cl − + I 2 The iodide ions lose electrons to form iodine molecules. In other words, they are oxidized. WebA reactivity series can be produced by attempting some displacement reactions. Different combinations of halogen solution and salt solution are tested. The table shows the results of these...
