What is Iodine pentoxide?

Chemical properties

needle shaped crystals

Physical properties

White crystals; hygroscopic; density 4.98 g/cm³; decomposes around 300°C;highly soluble in water; soluble in nitric acid; insoluble in ethanol, ether andcarbon disulfide.

The Uses of Iodine pentoxide

Oxidizes carbon monoxide to carbon dioxide with the formn of iodine (Ditte's reaction, which proceeds rapidly at 65° or above, but slowly at room temp). This reaction is used in gas analysis and for removing carbon monoxide from the air (in respirators preferably in presence of some H2SO4).

The Uses of Iodine pentoxide

Iodine (V) oxide is used as an oxidizing agent to remove carbon monoxide from gas.

Definition
