Rates of Reactions Investigation Aim The aim of our investigation is to investigate the rate of reaction between colourless solutions, hydrochloric acid and Sodium Thiosulphate by changing one of factors, which affect the experiment. Factors The factors, which affect this experiment, are: o The concentration of Sodium Thiosulphate o The concentration of Hydrochloric acid o The temperature of the solution Another factor I could have used is surface area, however this could only vary if we were reacting a solid and a liquid. The factor, which I have chosen to vary, is the concentration of the Hydrochloric acid. If I decided to change the concentration of both reactants, it would become quite complicated. This is why I am only varying the one factor. Therefore the concentration of the Sodium Thiosulphate will be fixed. Each group is given 60 ml of Sodium Thiosulphate, because this is not enough to complete the experiment, we will have to dilute this reactant...
