How does changing the concentration of sodium thiosulphate affect the rate of the reaction? By Richard Hek Introduction I have been asked to do an experiment into the rates of reaction to do this I am going to investigate how the concentration of sodium thiosulphate reacted with hydrochloric acid effects the rate of reaction. Aim: - To see the effects the concentration of sodium thiosulphate has on the rate of reaction when it is reacted with Hydrochloric acid. Neat solutions Sodium Thiosulphate + Hydrochloric acid Na2S2O3+2HCL Affecting concentration (Lowering concentration of sodium Thiosulphate) Water + Sodium Thiosulphate + Hydrochloric acid H2O+ Na2S2O3+2HCL Prediction I predict that as the concentration of sodium thiosulphate (Na2S2O3) increases the rate of the reaction will increase. This can be justified by relating to the Collision Theory. The collision Theory depicts that if the concentration is Higher there are more particles per unit and this means this is a higher chance of a successful collision with another particle. This...
