Iodine pentoxide is the chemical compound with the formula I 2 O 5. This iodine oxide is the anhydride of iodic acid , and one of the few iodine oxides that is stable. It is produced by dehydrating iodic acid at 200 °C in a stream of dry air: [ 1 ]
Iodine pentoxide (I 2 O 5) Iodine oxides are chemical compounds of oxygen and iodine. Iodine has only two stable oxides which are isolatable in bulk, iodine tetroxide and iodine pentoxide, but a number of other oxides are formed in trace quantities or have been hypothesized to exist. The chemistry of these compounds is complicated with only a ...
Liquid iodine trichloride conducts electricity, possibly indicating dissociation to ICl + 2 and ICl − 4 ions. [9] Iodine pentafluoride (IF 5), a colourless, volatile liquid, is the most thermodynamically stable iodine fluoride, and can be made by reacting iodine with fluorine gas at room temperature. It is a fluorinating agent, but is mild ...

Iodic acid features iodine in the oxidation state +5 and is one of the most stable oxo-acids of the halogens. When heated, samples dehydrate to give iodine pentoxide . On further heating, the iodine pentoxide further decomposes, giving a mix of iodine, oxygen and lower oxides of iodine.
The oxide is formed by the reaction of hot concentrated sulfuric acid on iodic acid for several days. [2]3HIO 3 → I 2 O 4 + HIO 4 + H 2 O. It is formed from diiodine pentoxide and iodine in concentrated sulfuric acid or iodosyl sulfate (IO) 2 SO 4 added to water: [3]
