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 WebSep 12, 2012 · Well, you can control the color of water with this little magic trick. Actually, it's not really magic, but a classic science experiment known commonly as the iodine clock reaction, which uses the reactions between water and chemicals to instantly colorize water, seemingly by command.
WebUnderstand how the initial rate of a chemical reaction producing iodine can be measured in an iodine clock reaction. Work up the data and calculate the rate constant at room temperature, the order of reaction with respect to Ferric and Iodide ions and the Arrhenius constant from rate law data.
