WebThe equations below are examples from a Hydrogen Peroxide Iodine Clock Reaction: Reaction 3: 〖2I〗_ (3 (aq))+starch →starch I_5 complex +I_ ( (aq)) (Shakhashiri, B. 1992). The first equation/reaction (determining step) shows that the iodide particles react with hydrogen peroxide to form triiodide ions. WebIodine Clock Reaction. Clock reactions are so called because they show a sharp dramatic colour change after a period of time has elapsed. They make ideal reactions for studying kinetics. Iodine clock reactions come in a number of variations, but they generally all use starch to show a sudden purple-black colour at the end of the reaction.
