Sodium Thiosulphate Coursework Aim The aim of this experiment is to investigate what affects the rate of reaction between Sodium Thiosulphate and Hydrochloric Acid. Factors There are four factors which affect the rate of reaction, these are: Concentration of liquids Catalyst Surface area * Temperature Chosen Factors The factor that I will base my experiment around is the temperature of the water and Sodium Thiosulphate. I will use this because: A catalyst is not required as the reaction is fast enough at room temperature Surface area is not a suitable factor to use in an experiment where only liquids are used. Concentration could be used, but I am examining temperature so I will use concentration in my preliminary work. Prediction I predict that the rate of reaction will increase as the temperature increases. I think this because as the temperature increases, the particles in the liquid have more energy and so move faster and cause more collisions. Therefore if the temperature doubles, the rate of...
