Our approach is a … Starch is often used in chemistry as an indicator for redox titrations where triiodide is present. Starch forms a very dark blue-black complex with triiodide. However, the complex is not formed if only iodine or only iodide (I ) is present. The colour of the starch complex is so deep, that it can be detected visually when the concentration of the iodine is as low as 20 µM at 20 °C. During iodine titrations, concentrated iodine solutions must be reacted with some titrant, often thiosulfate, in o… life cycle lapbook
