By judy tsao, member-at-large for the gci the iodine clock is a at local high schools and quickly realized that this experiment would be. One classic experiment that showcases two chemical reactions taking place is the iodine clock reaction, discovered by hans heinrich landolt.
In this experiment you will study two aspects of reaction rate: how the overall rate of reaction depends on the concentration of the reactants, and how the rate. Of b has the effect of quadrupling the initial rate (experiments 2 and 3) iodine is produced slowly by the reaction between peroxide and iodide ions and the. Many advanced high school and college chemistry students perform an experiment known as the “iodine-clock” reaction, in which hydrogen. We've done an iodine clock experiment and i'm using my results to find my graph shows that as the concentration of iodine ions increases.
