Web28 mrt. 2024 · An advanced experimental protocol is reported for studying the kinetics and mechanism of the complex redox reaction between chlorite ion and hypochlorous acid under acidic condition. The formation of ClO2 is followed directly by the classical two-component stopped-flow method. In sequential stopped-flow experiments, the target reaction is … Webreduced. In Equation 3, Iodine is reduced. Each of the two iodine atoms in I 2 gains one electron to form two iodide ions, I-.The zinc atoms cannot be oxidized without the presence of another chemical species, in this case iodine, which can be reduced. Thus iodine acts as an agent to carry out the oxidation of zinc and is therefore referred to as an oxidizing agent.
