WebThe iodine clock reactionis a classical chemical clockdemonstration experiment to display chemical kineticsin action; it was discovered by Hans Heinrich Landoltin 1886.[1] The iodine clock reaction exists in several variations, which each involve iodinespecies (iodideion, free iodine, or iodateion) and redoxreagents in the presence of starch.

Webtime it takes to produce the iodine/starch colour. The rate of the reaction can be determined by the reciprocal of time (because a constant amount of iodine is produced in each reaction) and a graph of the concentration of the variable under test against 1/t can be plotted. This graph can be used to determine the order of the reaction.
