Iodine thiosulfate redox titration
WebIodometric and Iodimetric Titration: Primary Differences. Iodometry is a titration in which the reducing agent is utilised to titrate the iodine formed in the preceding redox reaction, whereas iodimetry is a titration in which the reducing agent is used to titrate the iodine solution directly. Iodometry is a method of indirect analysis, whereas ...

WebIodine-Thiosulfate Titrations. A redox reaction occurs between iodine and thiosulfate ions: The light brown/yellow colour of the iodine turns paler as it is converted to colourless iodide ions. When the solution is a straw colour, starch is added to clarify the end point. The solution turns blue/black until all the iodine reacts, at which point ... Web11 apr. 2024 · Iodometry, known as iodometric titration, is a type of redox titration in which a solute (oxidizing agent) is added to excess iodide to obtain iodine, and the amount of iodine produced is determined by titration with a sodium thiosulfate solution. It's an indirect titration in which starch indicator is used to determine the endpoint.
