The indicator used in iodometric titration is
WebIodometric titration, also known as Iodometry, is a type of indirect titration. The analyte solution is an oxidizing agent in Iodometric titrations. It is reacted with an excess amount of potassium iodide (KI). The oxidizing agent oxidizes iodide (I–) ions into iodine (I2). WebOct 27, 2024 · Iodometry is one of the most important redox titration methods. Iodine reacts directly, fast and quantitively with many organic and inorganic substances. Thanks to its relatively low, pH independent redox potential, and reversibility of the iodine/iodide … In the cells it is easily oxidized to dehydroascorbic acid, removing oxidizing … Thus for the end point detection starch solutions are used.
