Melissa Taylor 11S Rates Of Reaction Coursework Introduction/ plan I am experimenting into the reaction rates of Sodium Thiosulphate and Hydrochloric acid when under different concentrations. Both Sodium Thiosulphate and Hydrochloric acid are clear solutions but when they react together they produce a cloudy solution, the solution become so cloudy you cannot see through it. To measure the rate of reaction I am going to print off a cross from the computer onto a piece of paper, place it under the beaker with the solution in it and record the time taken for the cross not to be visible. The Symbol equation for my experiment is: Na S O (aq) + 2HCl (aq) 2NaCl (aq) + H O (l) + S (s) + SO (g) The Word equation for my experiment is: Sodium Thiosulphate + Hydrochloric Acid Sodium Chloride + Water + Sulphur + Sulphur Dioxide Equipment Below is a list of the equipment I will be using throughout my...
