Iodimetry is used in the assay of
WebThis is called an iodometric titration. Most often of all, the reduction of iodine to iodide is the last step in a series of reactions where the initial reactions are used to convert an unknown amount of the solute (the substance being analyzed) to an equivalent amount of iodine, which may then be titrated. Web0.05M Iodine Procedure Weigh accurately about 0.1 gm of the sample and dissolve in a mixture of 100 ml freshly boiled and cooled water and 25 ml of 1M sulfuric acid. Immediately titrate with 0.05M iodine, using the starch solution as indicator until a persistent blue-violet color is obtained.
