Rates of Reaction AT1 Aim: To investigate the effect of changing the concentration of dilute Hydrochloric acid on the reaction between dilute Hydrochloric acid and Sodium Thiosulphate. Prediction (a): I predict that the more concentrated the acid is going to be the quicker the rates of reaction is going to happen. Prediction (b): This is because when there are more particles there would be more collision between the particles, Sodium Thiosulphate solution (Na2S2 O3 (aq)) and dilute Hydrochloric acid (HCL (aq)). Symbol Equation: Na2S2O3 (aq) + 2HCL (aq) 2NaCL (aq) + H2O (l) + So2 (g) + S (s) Word Equation: Sodium Thiosulphate + Hydrochloric acid Sodium Chloride + Water + Sulphur Oxide + Sulphur. During this reaction solid Sulphur is produced but it appears very slowly and at first there appears to be no reaction. After few moments the mixture slowly starts to turn cloudy and if the reaction vessels is placed over a...
