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 give we clock the reaction? We give guide the solution on top of the cross and add the chemicals to make growher. At this point, start the wind upwatch. The solution will begin to go cloudy. You should stop the watch when you bum no longer try the cross. What variables do we take up to throw? We need to control the temperature, this should be direction temperature. We need to make sure the raft of the acid is 10 cm3 and that the volume of Sodium Thiosulphate is 50 cm3. We will need to practise the same cross every time and that we riding habit 73g/l of concentrated hydrochloric Acid. How will I sort the concentration of Sodium Thiosulphate? We will change the concentration by diluting it with urine, we must constantly remember to keep the volume at 50 cm3. We need to do preliminary work to mark that we get a good range of results. We will use the value for the controlled variables we clear-cut above. Volume of Sodium Thiosulphate (cm3)         Volume of water (cm3)         Time 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 not profuse range of polar times betwixt 0.0 and 50.0 or 25 and 25 to fit 5 different concentrations in. so we can get between 50.0 and 0.0 and 10.0 and 40.0 to get a descent passel of concentrations.

Volume of Sodium Thiosulphate (cm3)         Volume of water (cm3)          assiduousn! ess (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 each try out three times. How will I be safe? I will obey the laboratory rules, as the experiment provides no particular danger.
