To see what factors affect the rate of reaction between Sodium thiosulphate and Hydrochloric acid Introduction: Sodium thiosulphate and hydrochloric acid react slowly to form a white/cream precipitate that makes the solution opaque. This reaction is not immediate, but gradually the white precipitate (which is sulphur) prevents you from seeing though the beaker to the surface of the bench. Na2s2o3 + 2HCL 2NaCl + SO2 + S + H2O The reaction between the sodium thiosulphate and the hydrochloric acid relies on successful collisions between these two reactants. A successful collision needs three important conditions to be satisfied: - 1) The reactant molecules must collide with each other. 2) The molecules must collide with the correct alignment. 3) The molecules must collide with enough energy to overcome the activation energy. This graph shows the energy needed for the activation energy as the reaction continues. After the activation energy is satisfied energy is given out and the...
