In order to determine the amount of a substance such as Vitamin C by titration, we can use iodometry methods. In this kind of process, iodine I 2 is titrated with sodium thiosulfate through ... WebIodimetry is a technique that involves titrating free iodine with a reducing agent. As a result, iodine decreases to iodide and oxidises other species. Because a free iodine …
WebIodometry titration is a method of analysis that uses iodine to determine the concentration of an analyte. This type of titration is also known as the direct method. In … 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.
