WebWhat is the purpose of sodium thiosulfate in a clock reaction?? Hazel99. ???? Reply 1. 6 years ago. It takes up the iodine produced. Once its used up, the iodine can react with other iodine ions to form a complex with starch- solution turns dark. By knowing how much thiosulhate you have, you can also determine the rate of reaction. Reply 2. WebThe reactions that form the basis for the iodine clock reaction are shown below. Equation 1: H2O2 + 3 I- + 2 H+ → I3- + 2 H2O • H2O2 = Hydrogen peroxide • I- = Iodide ion (from potassium iodide) • H+ = A proton, from hydrochloric acid (HCL) • I3- = Triiodide • H2O = Water Equation 1 shows that hydrogen peroxide reacts with iodide ...
Webcarried out in groups of 4-5 students. At standard conditions, the iodine clock reaction takes ~40 seconds to complete and ends with a stark transition from a colorless solution to dark blue/purple. Through modifying the temperature and reactant ratios, students can qualitatively observe the Arrhenius Equation and reaction orders of the reactants.
