The iodine clock reaction is a classical chemical clock demonstration experiment to display chemical kinetics in action; it was discovered by Hans Heinrich. A solution of hydrogen peroxide is mixed with one containing potassium iodide, starch and sodium thiosulfate. This is one of a number of reactions loosely called the iodine clock. This is the hydrogen peroxide/ potassium iodide ‘clock’ reaction. There are actually a couple of simple chemical reactions going on at the same time to make this “clock reaction” occur. This version of the classic “iodine clock.

Perform this experiment in a well-ventilated area. Observe The “Iodine Clock” reaction (sometimes called “Egyptian Night”) is an oxidation-reduction reaction. This reaction starts from a solution of hydrogen peroxide with sulfuric acid. To this is added a solution containing potassium iodide. It is important to note that the kinetics system we are working with is designed to be a demonstration of concepts of kinetics and not a kinetics experiment.
Iodine Clock Reaction. Hazards: WARNING: NEVER LET SOLUTION B STAND IN OPEN BEAKER FOR OVER AN HOUR. TEST EXISTING STOCK SOLUTIONS . In this science fair project, investigate the chemical kinetics of the famous iodine clock reaction. The study of kinetics using the iodine clock reaction has provided an interesting experience for students for many years. It sometimes proves frustrating for those.
One classic experiment that showcases two chemical reactions taking place is the iodine clock reaction, discovered by Hans Heinrich Landolt. This iodine clock experiment is so cool, we feel cheated that we never got to do it in high school chemistry lab. But it turns out the popular. The Iodine Clock Reaction a Simulated Experiment. by.
