Solution Calculating order with respect to HCl From the volume of the HCl used and the concentration of the stock solution of the HCl and volume of Na2S2O3 used we need to calculate new concentrations of the HCl in each trial after mixing the solutions So lets calculate the final concentration of the HCl Trial 1 Drops of HCl 12 drop Drops of Na2S2O3 8 drop Water drops 0 Final concentration of HCl See Answer
