An Investigation into the Factors that Effect the Rate of Reaction Between Hydrochloric Acid and Sodium Thiosulphate. Aim: *- Investigating the diverse factors that affect the rate of a reaction, by monitoring the effect of varying concentrations on reactants. In this experiment I am going to find out how the rate of reaction between sodium thiosulphate and hydrochloric acid is affected by changing the concentration. The equation to this is as follows: Sodium + Hydrochloric = Sodium + Sulphur + Sulphur + Water Thiosulphate Acid Chloride Dioxide Na2S2O3 (aq) + 2HCL (aq) = 2NaCl(aq) + SO(g) + SO2(s) + H2O(l) This reaction usually produces a yellow precipitate. Preliminary Work: *- Previous to my final experiment, I conducted a prior procedure to confirm a relevant range of readings. In order for me to provide myself with not only accurate, however also relevant information, I felt it appropriate to perform various personal assessments in order to provide...
