Experiment to Investigate the Rates of Reaction between Sodium Thiosulphate Solution and Dilute Hydrochloric Acid
I am going to be doing an experiment to study the rate of reaction between sodium thiosulphate solution and dilute hydrochloric acid.
The chemical equation for this reaction is:
Na2S2O3 (aq) + 2 HCl (aq) ? S (s) + SO2 (g) + 2 NaCl (aq) + H2O (l)
During this chemical reaction there is a slow formation precipitate of solid sulphur. As a result, the solution in which the reaction is taking place gets gradually cloudier. The time the reaction takes to reach a certain point of cloudiness can be measured, by placing the flask over a white sheet of paper onto which a black cross is drawn. Eventually the solution will become so cloudy that you can no longer see the cross. In this way you can study the rate of reaction (how fast it goes under different conditions).
I predict that the higher the concentration of sodium thiosulphate solution, the quicker the rate of reaction will be to produce solid sulphur, which is the precipitate formed from the chemical reaction. So, the more dilute the
