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
