what does iodine react with
Reaction of iodine with air. Iodine, I 2 is not reactive towards with oxygen, O 2, or nitrogen, N 2. However, iodine does react with ozone, O 3, the second allotrope of oxygen, to form the unstable yellow I 4 O 9, the nature of which is perhaps I(IO 3) 3.
Iodine, I 2, reacts with fluorine, F 2, at room temperature to form the pentafluoride iodine(V) fluoride. At 250Â°C the same reaction affords the heptafluoride iodine(VII) fluoride.
