The effect of temperature upon the rate of reaction between Sodium Thiosulphate and Hydrochloric acid Plan I am going to be measuring the effect of temperature upon the rate of reaction between Sodium Thiosulphate and Hydrochloric acid. A yellow precipitate is produced in the reaction between the two chemicals in question. Na S O (aq) 2HCl(aq) 2NaCl(aq) S(s) SO (g) H O The rate of reaction can be seen by recording the time taken for a given amount of sulphur to be precipitated. I will do this by placing a conical flask containing the reaction mixture onto a cross on a piece of paper. As the precipitate of sulphur forms, the cross is obscured and finally disappears from view. The time taken for this to happen is a measure of the rate of reaction. To get enough information on the effect of changing the temperature of the reactants, several experiments must be done,...
