WebThe iodine clock reaction is a classical chemical clock demonstration experiment to display chemical kinetics in action; it was discovered by Hans Heinrich Landolt in 1886. The iodine clock reaction exists in several variations, which each involve iodine species and redox reagents in the presence of starch. Two colourless solutions are mixed ... 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.
