| Iodine pentoxide Usage And Synthesis |
| 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 and carbon disulfide.
| | Uses | Iodine pentoxide is used for analysis of carbon monoxide and for CO removal from air. It also is used as an oxidizing agent in other oxidation reactions.
| | Preparation | Iodine pentoxide is prepared by dehydration of iodic acid at 240°C.
2HIO3 → I2O5 + H2O
| | Reactions | Iodine pentoxide is a strong oxidizing agent and reacts with various oxidizable substances. It oxidizes carbon monoxide to carbon dioxide. The reaction is quantitative and used to measure carbon monoxide in the air:
I2O5 + 5CO → I2 + 5CO2
It reacts with hydrogen sulfide, forming sulfur dioxide:
3I2O5 + 5H2S → 3I2 + 5SO2 + 5H2O
Oxidation reaction also occurs with hydrogen chloride, metal hydrides and a number of metal salts. It dissolves in water reacting to form iodic acid:
I2O5 + H2O → 2HIO3
Dissociation into iodine and oxygen commences when heated above 270°C.

This reaction is used in gas analysis and for removing carbon monoxide from the air (in respirators preferably in presence of some H2SO4). |
