Investigate the effect of the concentration of the disodium thiosulfate solution on the rate of the process
Na2S2O3 + H2SO4 = Na2SO4 + SO2 + H2O + S.
Prepare a control sample by adding 1 cm^3 of sulfuric acid solution to 3 cm^3 of Na2S2O3 solution. Pay attention to the upcoming changes.
Pour 1 cm^3, 2 cm^3 and 3 cm^3 of Na2S2O3 solution into three test tubes respectively. Using a pipette (or syringe), add 2 cm^3 of water to the first tube, and 1 cm^3 of water to the second. Thus you get three solutions of equal volume and different concentration.
To each of the tubes successively add 1 cm^3 of sulfuric acid solution and note the time for the solution to darken from the sulfur released during the reaction. Record the results of each experiment in the table.
Graphically represent the relationship between the reaction time and the concentration of Na2S2O3 (∆t = f1(c)).
Represent the graphical dependence 1/∆t = f2(c).
Based on the graphs, draw a conclusion about the effect of concentration on the rate of the reaction.
