Chemistry investigation: Rates of reaction when decolourising acified potassium permanganate. Introduction Over a period of several lessons, we planned an executed an experiment, so as to investigate what variables affect the rate of reaction when decolourising acified potassium permanganate with glucose. It would be easy to tell when the reaction has finished because we would be left with a colourless solution. There are only two feasible variables with which we are conducting the experiment that can be changed. These are the temperature at which the reaction takes place and the concentration of glucose used to react the substances. For the duration of this particular experiment I chose to change the concentration of glucose. Prediction My prediction is that the higher the concentration of glucose present in the experiment the faster the reaction will take place. The reason the reaction will go faster is that if there is a higher concentration of glucose there are...
