Chemistry Coursework Rebecca Newiss Aim I will be investigating the rate of reaction between Sodium Thiosulphate and Hydrochloric acid. I intend to find the difference in the rate of reaction when I change the concentration of the Sodium Thiosulphate, as I am only changing the concentration of the Sodium Thiosulphate I will keep the concentration of Hydrochloric acid the same at all times. Hydrochloric + Sodium Water + Sodium + Sulphur + Sulphur Acid Thiosulphate Chloride Dioxide 2HCl + Na S O H O + 2NaCl + SO + S Prediction I predict that from this experiment I will find that the weaker the concentration of Sodium Thiosulphate is to the concentration of Hydrochloric Acid, the longer the reaction will take to occur. Theory In my prediction I have stated that, the weaker the concentration of Sodium Thiosulphate is to the concentration of Hydrochloric Acid, the longer the reaction will take to occur. In my opinion this will...
