GCSE Chemistry Coursework Aim: to find out how changing the concentration of Sodium Thiosulphate in a sodium thiosulphate and hydrochloric acid solution effects the reaction rate. Planning the experiment. Apparatus: Conical flask Paper with a cross on 35ml of Hydrochloric Acid 245ml of Sodium Thiosulphate 2 Measuring cylinders 180ml of tap water Stopclock Prediction: I predict that the more sodium thiosulphate in the solution, the faster reaction rate will be. This is because the solution must be concentrated so that bonds can be broken quicker. The more collisions in a given time, the faster the reaction will be. The reactants must hit each other hard to break bonds so this is why the solution must be very concentrated. Not all the collisions result in bonds breaking but the higher the concentration then the more collisions there will be and so there will be a higher chance of more collisions happening. Planned method: We had done preliminary work which I have...
