Investigating the rate of reaction between Sodium Thiosulphate and Hydrochloric Acid Diagram Aim : We did 4 experiments to find out how the rate of reaction changes with differing concentrations of Sodium Thiosulphate, Hydrochloric Acid and water. As an inert and stable liquid, water was used to alter concentration of Sodium Thiosulphate without changing the end amount of solution. All the atoms in a water molecule have a full outer shell, so they would not react with …showed first 75 words of 1532 total…

One thing I would be hard pushed to overcome would be the light that passes down through the glass sides of the beaker, via TIR. This is however not that important, as any light entering the light sensor via this route would remain constant.
