WebTHEORY. In iodimetry, quantitative oxidation of reducing agents, such as arsenious acid (H 2 AsO 3) may be carried out by employing standard solutions of iodine as shown under :. This type of assay is known as ‘direct method of iodimetry’.. In another situation, a known excess quantity of standard iodine solution is added in the substance (a reducing agent) … Web15 nov. 2010 · However, these methods require special reagents and involve multi-step reactions. Estimation of iodate in iodised salt by transient isotachophoresis-capillary zone electrophoresis has been reported recently (Wang, Zhao, Shen, & Wang, 2009). The method is useful and gives precise results with chromate ion as an internal standard.
