Reaction between thiosulfate and iodine
WebThe reaction between iodide and hydrogen peroxide produces triiodide. The triiodide ions are reduced back to iodide by thiosulfate at a much faster rate, until the thiosulfate is consumed. Then the triiodide ions form a blue starch-pentaiodide complex, causing the solution to turn from clear to dark. Websimultaneously forming iodine, and if the iodine is subsequently titrated with thiosulfate, the technique is iodometry. Iodometry is an example of an indirect determination since a product of a preliminary reaction is titrated. The use of iodine as a titrant suffers from two major disadvantages. First, iodine is not
