Investigate the Kinetics of the Color Changing Iodine Clock Reaction

WebThe slow steps in the overall reaction are assumed to be the formation of iodine (Equations 1 and 2). Iodine formed in the slow step is quickly consumed by a very fast reaction with bisulfite ions (Equation 3). The blue color does not appear, therefore, until all of the bisulfite ions have been consumed. Bisulfite ions are the limiting reactant and WebJan 13, 2024 · This reaction starts from a solution of hydrogen peroxide with sulfuric acid.
