Synopsis

This laboratory report gives an outline of the experiment which was carried out in order to determine a reaction rate expression between hydrogen peroxide and acidified potassium iodide using an initial rate method. The lab consisted of three experiments and each of them was carried out twice. In each experiment the mixture of KI, H2SO4, Na2S2O3, H2O, H2O2 and starch solution was prepared and time was recorded when the blue colour appeared. Then the average time for each experiment was found. In the next step the inverse times were calculated which
