Friday 28th November Chemistry Coursework Aim The purpose of this experiment is to see how the concentration of hydrochloric acid affects the rate of reaction when mixed with sodium thiosulphate. Introduction I have been assigned the task of recording, and understanding how the concentration of acids affects their rate of reaction. The experiment will be conducted under the rules of a fair test and will involve mixing sodium thiosulphate with different concentrations of hydrochloric acid. The solution, stored in a beaker, would then be placed above a light sensor, which would then record the amount of light passing through the solution. Once the light sensor takes a final, definite reading this indicates that the reaction has finished. I then have to record the time, in which the solution turns misty restricting light from reaching the sensor and also record the percentage of light reaching the sensor as well. In my coursework I should...
