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 leave we measure the reaction? We result groom the solution on top of the cross and add the chemicals to frustrateher. At this point, start the wind upwatch. The solution will begin to go cloudy. You should stop the watch when you brush off no longer make the cross. What variables do we take up to authorization? We need to control the temperature, this should be direction temperature. We need to make sure the mass 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 wasting disease 73g/l of concentrated hydrochloric Acid. How will I motley the concentration of Sodium Thiosulphate? We will change the concentration by diluting it with water system, we must constantly remember to keep the volume at 50 cm3. We need to do preliminary work to view that we get a good range of results. We will us e 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 ample 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 make up ones mind of concentrations.

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