Chemistry Coursework The reaction between Sodium Thiosulphate and Hydrochloric Acid Aim: In this investigation, we are trying to determine the effect that changing the concentration of the hydrochloric acid has on the rate of reaction between sodium thiosulphate and hydrochloric acid. We have chosen to measure how long it takes before the solution becomes cloudy and the light beam is no longer detected through it. We can do this by using light gates attached to a computer that will record the results on a graph. Prediction: I believe that the greater the concentration of hydrochloric acid, the less time it will take before the light beam is no longer detected through the solution. When the acid is pure and isn't diluted at all then the reaction should be the quickest. When the acid is the weakest then the reaction will be slower because the concentration of the molecules isn't as much and so...
