Investigate How the Concentration of Hydrochloric Acid And Sodium Thiosulphate Affects the Rate of Reaction My aim is to investigate the effects of mixing two solutions together. Prediction I predict that if the concentration of any solution is altered, it will affect the rate of reaction. In this case, if increasing it changes the concentration of Hydrochloric Acid or Sodium Thiosulphate, then the reaction is faster. If the concentration of either substance is decreased, then the reaction will be slower, and the rate of reaction will be reduced. The concentration being higher would enable the particles to collide and gain more energy, making the reaction quicker. Sodium Thiosulphate has a greater effect on the rate than the Hydrochloric Acid because the sulphur formed comes from the Sodium Thiosulphate. Safety For safety, I will make sure that I wear safety goggles whilst carrying out the experiment, and to make sure my hair is tied back so that...
