Iodine clock reaction simulation
WebThe first reaction produces I 3-. When I 3-comes in contact with starch (in reaction three) it produces a characteristic blue/black color. However, before that can happen S 2 O 3 2-reacts with it to produce colorless products (in reaction two). Because reaction two is much faster than reaction three, the third reaction won’t take place until ... http://introchem.chem.okstate.edu/DCICLA/Iodine%20Clock.pdf

WebChemical Kinetics Simulation Overview The iodine clock reaction is a famous experiment first performed by Hans Landolt in 1886. In this lab you will study the kinetics of the following reaction between iodide and persulfate ion: 21' + S2O32- → 12+2 SO42 (1) In this reaction, iodide is oxidized to elemental iodine by reaction with persulfate.
