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. WebEXPERIMENT 13: THE IODINE CLOCK REACTION Background In this experiment you will study the rate of the reaction between iodide ion, I–, and persulfate (peroxydisulfate), S2O82–. The products of the reaction are I2and sulfate ion. Write the balanced chemical equation for this reaction in the space provided.
