James Pearson 11h Investigation into rates of reaction decolourising acidified potassium permanganate with glucose Introduction During the course of several lessons we planned and executed an experiment to investigate the rates of reaction decolourising acidified potassium permanganate with glucose. After a short amount of time we would be able to determine whether or not the reaction had finished because the solution would become colourless. When conducting this experiment, one should consider the two following variables: the temperature of the solution and the concentration of glucose in the experiment. For the duration of this particular experiment I chose to vary the concentration of the glucose. Prediction I predict that the higher the concentration of glucose in each solution, the faster it will react with the potassium permanganate. This is because glucose breaks down the particles of potassium. This will cause the solution to decolourise over a smaller interval of time. The solution is purple before...
