WebIodine clock reaction demonstration method Experiment RSC Education Use this iodine clock reaction demonstration to introduce your students to rates of reaction and kinetics. … WebIn this experiment, iodine clock reaction was performed to represent a chemical kinetic scheme. Different concentration of -I , BrO 3-, and H+ were primary reactants by using thiosulfate’s consumption in reaction to iodine, which then reacted with starch to show an appearance of blue coloration as representation of the reaction.
