GCSE SCIENCE COURSEWORK (CHEMISTRY) PLANNING: Skill Area P Write down the aim of your Investigation. To investigate the effects of change in concentration on the rate of reaction between Sodium Thiosulphate and Hydrochloric Acid. Briefly describe your Preliminary Experiment and include your results. Explain how these results have helped you plan your main experiment (p8b). An increase in concentration will lead to an increase in the rate of reaction because there will be a …showed first 75 words of 2410 total…

Moreover I will compare my results with those of my peers and also use results and findings of previous scientific research in this field of study to further verify my conclusions. Lastly, I intend to take the investigation one step further by not only identifying the effects of change in concentration on the rate of reaction but also to study the rate of reaction itself.
