The Reaction Between Sodium Thiosulphate and Hydrochloric Acid
The Effect on the concentration on the reaction between Sodium Thiosulphate and Hydrochloric acid

I would also ensure that the 1 molar solution of Sodium Thiosulphate that we began with was accurate. I would preferable make it myself and if this wasn't possible definatly make sure each sample of the solution used was from the same bottle that had been made. As each bottle could be slightly different, this could have an effect on the results.
I think we carried out enough experiments to get a reliable average for each concentration, although the more results we took the more accurate the average would have been as it would have more data to be worked out from. I think that if we wanted to ensure a totally reliable average we should conduct more experiments.
The method we used was detailed and gave a reliable and accurate set of results which have been presented in graphs and tables. All this evidence, plus previous scientific knowledge and the use of secondary sources, has proven my hypothesis that as the concentration increases, the time for the reaction to take place decreases.
Overall I think the experiment went well and we have completed what we had initially aimed to do, plus looked at a bit extra. We have …show more content…
We predicted that this would also increase the rate of reaction as the particles would have more kinetic energy therefore would make more collisions. This is because the particles would have more kinetic energy as explained in my planning.
To carry out this experiment we used a set solution of Na2S2O3 and H2O and added this, after heating to HCl. We heated each solution to separate temperatures at intervals of 10°C. We stopped at 80°C for safety and ensured each participant was wearing goggles. We recorded the temperature when the HCl was added and then when the reaction had finished to see if this was altered in anyway. We also looked at the difference between each temperature and this would be displayed on a graph. We also took two results for each temperature so we could find an average. We took an average because the experiment was not done under controlled conditions. For example different people were doing each experiment. For more reliable results we should have taken more readings, this would be more important n this situation as the experiments were not done
