Iodometry endpoint

Webendpoint. Some redox titrations do not require an indicator, due to the intense color of the constituents. For instance, in permanganometry a slight persisting pink color signals the endpoint of the titration because of the color of the excess oxidizing agent potassium permanganate.[31] In iodometry, at sufficiently large Web3. Once the brown colour of Iodine becomes hard to discern from transparency, add starch indicator to determine the final endpoint of the Sodium Thiosulfate titration. (This …
