Iodate 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 shows no tendency to disproportionate to periodate and iodide, in contrast to the situation for chlorate. Iodate is reduced by sulfite: Iodate oxidizes iodide: WebA redox couple is a reducing species and its corresponding oxidizing form, [6] e.g., Fe 2+ / Fe 3+ .The oxidation alone and the reduction alone are each called a half-reaction because two half-reactions always occur together … WebLes ions iodure réagissent aussi avec l'eau oxygénée H 2 0 2 suivant la réaction d'équation : H 2 0 2 + 2H + (aq) + 2 I-aq = I 2 aq + 2H 2 O.
