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 allow we fourth dimension the reaction? We go away target area the outcome on eliminate of the cross and add the chemicals together. At this point, start the wind upwatch. The solution depart begin to go cloudy. You should stop the watch when you stop no longer chew the fat the cross. What variables do we take up to mastery? We essential to control the temperature, this should be direction temperature. We need to make sure the al-Quran of the acid is 10 cm3 and that the intensity level of sodium Thiosulphate is 50 cm3. We result need to practise the aforesaid(prenominal) cross every clock and that we affair 73g/l of unvoiced hydrochloric Acid. How will I veer the concentration of Sodium Thiosulphate? We will change the concentration by diluting it with water, we must constantly mobilise to keep the volume at 50 cm3. We need to do preliminary work to hear that we get a legal range of results. We will use the value for the controlled variables we clear-cut above. intensity level of Sodium Thiosulphate (cm3)         Volume of water (cm3)          fourth dimension 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 icy times betwixt 0.0 and 50.0 or 25 and 25 to plump 5 different concentrations in. so we can get amidst 50.0 and 0.0 and 10.0 and 40.0 to get a line of products 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 distributively try out lead times. How will I be safe? I will come after the laboratory rules, as the taste provides no particular danger.
