Iodine clock reaction purpose
Web6 dec. 2005 · A clock reaction produced by mixing chlorate and iodine solutions in perchloric acid media is reported. This is the first example of a clock reaction using … WebThe reaction in this experiment is termed an iodine clock reaction, because it is the molecular iodine (12) that undergoes the sudden concentration change. When the iodine concentration increases, it reacts with iodide ions to form the linear triiodide ion (13) which inserts itself within the starch to form a complex, turning it a deep blue-black color.
