Web28 mei 2004 · The iodate/iodide amplification reaction is very fast in acidic solutions and so can readily be studied in a flow system. The detection wavelength is chosen to the 351 nm instead of employing UV region 290 nm. The determination of iodide is based on oxidizing iodide to iodate. WebIodate has been reported as present in drinking water at various levels (Nyman et al., 1996; Weinberg and Yamada, 1998). Although the levels are low, it has been speculated that the presence of iodate and, by implication, iodide can have far-reaching consequences on water quality through the formation of iodine-substituted organic by-products ( Plewa et …

One example of a reversible reaction is the reaction of hydrogen gas and iodine vapor to form hydrogen iodide. The forward and reverse reactions can be written as follows. 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.
