WebClock Reaction (4 points) In this experiment you will investigate the kinetics of the reaction between persulfate and iodide ions S 2 ... (R1) The rate of reaction may be measured by adding a small, known quantity of thiosulfate. The iodine produced in this reaction (R1) is, as it is formed, reduced back to iodide by the thiosulfate: 2S 2O 3 2 ... WebThe “Iodine Clock” reaction (sometimes called “Egyptian Night”) is an oxidation-reduction reaction. Colorless solutions are mixed and, following a short pause, the liquid rapidly turns dark blue, almost black. Several oxidation-reduction reactions take place in the solution ...
WebWhen carrying out a clock reaction, we assume that: Changes in reactant concentration are insignificant; Temperature does not change; The end point is reached before the reaction has gone too far . The Iodine Clock Reaction. 1.Iodine is produced. Sulfuric acid is mixed with potassium iodide solution to produce a mixture of H+ and I- ions. Webdetermine the effect of a catalyst on the rate of reaction. Discussion When hydrogen peroxide is added to a solution of potassium iodide, the iodide ions are slowly oxidized according to the equation: 22 2 2 potassium iodide hydrochloric acid hydrogen peroxide iodine colorless colorless coloroless yellow-+ iodide
