The Iodine Clock Investigation Introduction This is an investigation into the rate of a reaction and the factors that contribute to how fast a reaction will take place. Through the recording and analysis of raw data‚ this investigation also allows us to apply generally accepted scientific rules and to test them against results gained from accurate experimental procedures. Aim The aim of this experiment is to investigate the rate at which iodine is formed when the concentration

produced. This iodine will be converted into I3- which will react stoichiometrically with the thiosulfate. The thiosulfate to be used for titration was first standardized using KIO3 as the primary standard. KI crystals and sulfuric acid was added to the KIO3 solution one after the other. KI crystals should be added first or the solution may produce more O2 and add to the analyzed dissolved oxygen of the sample: The resulting solution was titrated right away with Na2S2O3 as the titrant and starch
