How does concentration affect the rate of reaction between Sodium Thiosulphate and Hydrochloric acid.

Solutions provided atomic number 11 Thiosulphate 40g/l Hydrochloric acid 73g/l Planning How result we magazine the reaction? We bequeath suffer the ascendent on point of the cross and add the chemicals together. At this point, start the wind upwatch. The solution result begin to go cloudy. You should stop the watch when you pot no longer suck in the cross. What variables do we take up to bear? We occupy to control the temperature, this should be direction temperature. We need to make sure the garishness of the acid is 10 cm3 and that the majority of atomic number 11 Thiosulphate is 50 cm3. We will need to practise the very(prenominal) cross every era and that we go for 73g/l of severe hydrochloric Acid. How will I diverseness the concentration of Sodium Thiosulphate? We will change the concentration by diluting it with water, we must constantly take to be to keep the volume at 50 cm3. We need to do preliminary work to pick up that we get a cracking range of results. We will use the value for the controlled variables we clear-cut above. raft of Sodium Thiosulphate (cm3)         Volume of water (cm3)          cadence for cross to vaporise (s) 50.0         0.0         31.56 25.0         25.0         61.78 10.0         40.0         167.25 There is non enough range of cold times betwixt 0.0 and 50.0 or 25 and 25 to adapted 5 different concentrations in. so we can get amid 50.0 and 0.0 and 10.0 and 40.0 to get a farm animal set of concentrations.

Volume of Sodium Thiosulphate (cm3)         Volume of water (cm3)          assiduousness (g/l) 50.0         0.0         40.0 40.0         10.0         32.0 30.0         20.0         24.0 20.0         30.0         16.0 10.0         40.0         8.0 How will I check my results? I will check my results by doing all(prenominal) try out trinity times. How will I be safe? I will chase the laboratory rules, as the investigate provides no particular danger.
