Effect of concentration on rate of reaction Aim The investigation is about the effect of concentration on the rate of chemical reaction. In this experiment I am going to investigate the rate of reaction of sodium litho sulphate with hydrochloric acid. The reaction that I will use is: Sodium litho sulphate + Hydrochloric Acid Na2S2O3 + 2HCl Variables I will change the concentration of hydrochloric acid each time. I will use hydrochloric acid 0.1M, 0.25M, 0.50M, 0.75M and 1M. I will keep the same the amount of hydrochloric acid and sodium litho sulphate concentrations used. I will be measuring the time it takes the sodium litho sulphate to react with hydrochloric acid to form sulphur (a cloudy white colour). Prediction What I think might happen is that the concentrations will mix together and then the concentration will turn to a cloudy colour after it has been mixed. So the smaller the concentration is, the slower the reaction will happen. My reasons...
