WebIodometric Titration Method Iodometric titration assay, which is based on the oxidation of the iodide ion (1 ) by hydroperoxides (ROOH), is the basis of current standard methods for determination of PV (9). In this method, a samrated solution of potassium iodide is added to oil samples to react with hydroperoxides. WebExample: Copper sulfate (CuSO 4) solution is the analyte solution, so we will base this Iodometric titration on finding the exact amount of Cu 2+ ions. Step II: Add an excess …
WebIodometry is a titration where the iodine produced in the previous redox reaction is titrated with a reducing agent whereas iodimetry is a titration where iodine solution is directly titrated with the reducing agent Iodometry is an indirect method of analysis whereas iodimetry is a direct method of analysis WebAboutTranscript. A redox titration is a titration in which the analyte and titrant react through an oxidation–reduction reaction. As in acid–base titrations, the endpoint of a redox titration is often detected using an indicator. Potassium permanganate (KMnO₄) is a popular titrant because it serves as its own indicator in acidic solution.
