The reaction rate can be determined by measuring the time it takes a colourless solution to turn yellow. In an experiment to determine the effect of concentration on reaction rate, a constant volume of HCl solution with a concentration of 2 mol.dm-3 is added to a constant volume of Na2S2O3 solutions of varying concentrations. Consider the graphs below of the various experiments carried out. Which combination of graphs represent the following: Concentration of sodium thiosulphate (y-axis) vs t (for solution to turn yellow) Concentration of sodium thiosulphate (y-axis) vs (for solution to turn yellow) A. Z Y B. W X C. Y W D. W Z 1.7 Identify the two substances that act as Brønsted-Lowry bases in the equation below. HS- + SO42- ⇌ S2- + HSO4- A. HS- and S2- B. SO42- and S2- C. HS- and HSO4- D.
