Chemistry Coursework Rate of Reaction Experiment Na S O (aq) + 2HCL (aq) › 2NaCl (aq) + H O (l) + SO (aq) + S (s) Sodium Thiosulphate + Hydrochloric Acid › Sodium chloride + Water + Sulphur Dioxide + Sulphur About the experiment before doing it: If we put a certain amount of Sodium Thiosulphate (liquid) with a certain amount of Hydrochloric acid (liquid), a reaction will occur; the liquid mixture of these chemicals will become cloudy, and we decided to put a white paper underneath the flask and draw (or put) a cross on it, then measure the time that it will take to let the cross disappear. We want to find out how the concentration of Thiosulphate solution affects the rate of reaction. Concentration of: Na S O = 40g dm3 = 0.25 mol dm3 ( Sodium Thiosulphate ) HCL = 2 mol dm3 ( Hydrochloric...
