Web23 apr. 2024 · This microorganism is common in biotechnological processes such as bioleaching and biooxidation of minerals, in which there is accumulation of ferric ions (Fe 3+) that results from the energy obtaining reactions of the cell. At. ferrooxidans can be inhibited by ferrous (Fe 2+) and ferric (Fe 3+) ions, being stronger the last one. 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 :
