Sandeep Brar 10D2 Investigating reaction rates of Sodium Thiosulphate and Hydrochloric acid Aim: To investigate the rate of reaction of Sodium Thiosulphate and Hydrochloric acid. In this investigation I will be varying the concentration of Sodium Thiosulphate only and not the Hydrochloric acid concentration. In this investigation I will use the following word equation: Sodium Thiosulphate + Hydrochloric acid In this investigation I will use the following symbol equation: Na2S2O3 + Hcl Prediction: I predict that as the Sodium Thiosulphate concentration increases the rate of reaction will also increase. The reason I predict this is because there will be a higher concentration of particles and so a faster reaction would be able to occur- so the reaction rate would increase. There will be more particles of Sodium Thiosulphate and Hydrochloric acid in a small volume and so more collisions are likely to occur which in turn cause a quicker rate of reaction. In this investigation I used 25cm cubed...
