Web27 feb. 2014 · Reaction Kinetics: The Iodine Clock Reaction Introduction The “clock reaction” is a reaction famous for its dramatic colorless-to-blue color change, and is often used in chemistry courses to explore the rate at which reactions take place. The color change occurs when I 2 reacts with starch to form a dark blue iodine/starch complex.

WebReactions A1-A3 dominate (A3 is very fast) until all HSO3- is consumed. I3- is consumed as fast as it is produced, preventing the blue I5--starch complex from forming. When HSO3- is gone, reaction B takes over and I3- and starch immediately react to form the blue complex. To Conduct Demonstration: I.
