Hypothesis:
In the investigation of the rate of reaction and concentration of Sodium Thiosulphate. I predict that the higher the concentration of sodium thiosulphate solution, the faster the rate of reaction because if the solution is made more concentrated it means there are particles of reactant knocking about between the water molecules. This makes collisions between the important particles, more likely. I also predict the sulphur precipitate will turn the solution a cloudy yellow and will vague the cross x.
