WebIodate is one of several oxyanions of iodine, and has an oxidation number of +5. It participates in several redox reactions, such as the iodine clock reaction. Iodate show no tendency to disproportionate to periodate and iodide, in contrast to the situation for chlorate. Iodate is reduced by sulfite: [1] Iodate oxidizes iodide : Web3. The reverse reaction must be suppressed. Forward reaction: 2I– + 2H+ + H2O2 → I2 + 2H2O Reverse reaction: I2 + 2H2O → 2I – + 2H+ + H2O2 (negligible) If the concentration of iodine (I2) is allowed to build up as the reaction proceeds then the rate of the reverse reaction will increase and an equilibrium mixture will result.
