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. WebThe process by which estimation of oxidant or reductant is made by the use of liberated iodine is called iodometric titration. In this experiment, a standard solution of potassium … WebMay 9th, 2024 - Procedures for standardization of iodine and thiosulfate solutions used in iodometric titrations Titration and titrimetric methods sources of errors ... this analysis you add an excess of standardized acidified potassium dichromate solution to the wine which converts the ethanol to ethanoic acetic acid iowa form 65-5300
