| 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. |
| 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. |
| Uses | Iodine (V) oxide is used as an oxidizing agent to remove carbon monoxide from gas. |
| Uses | 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). |
| Definition | ChEBI: Diiodine pentaoxide is an iodine oxide. |
