The first task is to calculate the volume of Ce 4+ needed to reach the titration’s equivalence point. From the reaction’s stoichiometry we know that moles Fe2 + = moles Ce4 + MFe × VFe = MCe × VCe Solving for the volume of Ce 4+ gives the equivalence point volume as

Web11 apr. 2024 · 2.2.Determination of iodine in table salt by iodometric titration. The iodine level of each of the 3,600 salt samples was measured using the WHO-recommended iodometric titration method (Kumar Nepal et al., 2013, World Health Organization, 2007).A conical flask was weighed electronically and then filled with 10 g of salt, 50 ml of … 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. softwell automation
