WebIn clock reactions, they contain a complex mixture of chemicals which react in order to cause a physical change after a period of time (Faculty, 2015). The term clock reaction comes from the time taken for a quantity of product to form changes when the concentration of one of the reactants varies, due to different physical changes occurring at different … WebClock reactions often appear in chemistry shows, and many involve iodine, since the colour change resulting from the generation of iodine is particularly marked. However, …

WebKinetics and Pseudo-Order Conditions. As you have seen in class and in your textbook (Silberberg sections 14-2 & 14), the rate of reaction can be related to the reactant concentrations through an expression called the rate law for a particular reaction. For the iodine clock reaction studied in this experiment the general form of the rate is:
WebIn this experiment, we'll investigate a reaction called the "iodine clock." Aqueous solutions of potassium iodate (K103) and sodium hydrogen sulfite (NaHSO3) react in acidic solution and produce elemental iodine, sulfate ion, and water. 5 HS03 (aq) + 2 103 (aq) 12 (aq) + 5 SO ?
