Iodine thiosulfate redox titration
WebThe amount of hypochlorite ion present in a solution of bleach can be determined by an oxidation-reduction titration using iodine and thiosulfate ions. The iodide will be oxidized [2I−(aq) → I 2 (aq) + 2e−] due to its low reduction potential relative to … Web19 mei 2024 · This method uses volumetric chemical analysis. The iodine will later be released in the presence of a reaction with the analyte / titrate. This titration process will …
