1. Use equation (3) and the titration results of runs 13 to calculate the distribution constant, k. You will need to calculate the concentration of iodine in the organic phase and also in the aqueous phase from the titration with the thiosulfate solution. Keep in mind that the reaction that takes place in the titration is: 2SO2()+ISO2()+2I()23246 Consider the stoichiometric ratio 1:2 and the volumes used for the samples (organic layer, 10mL and aqueous layer, 30mL. 2. Plot k versus the iodine concentration in the organic solution, [12]org. If k is not constant, discuss its dependence on concentration. 3. Using equations (4). (5) and (6) and the results from runs 4-6, calculate the equilibrium concentrations of 12,13and Iin each run. In each case, use the appropriate value of k as read from the k vs. [12]org plot that you obtained in step 2. The reactions that take place during the titration with thiosulfate ion are: 2SO2()+ISO2()+3I(q)233462SO2()+ISO2()+2I()23246 We can see that the stoichiometric ratio between thiosulfate ion and cither iodine ion or triiodide ion is the same, 2:1. Take this ratio into account when calculating T from the titration of the samples, as well as the volumes of the samples (organic layer, 10mL and aqueous layer, 30mL ) and the concentration of the thiosulfate solution (0.01M or 0.1M) used. 4. Calculate the equilibrium constant with the equilibrium concentrations for runs 46. Discuss any concentration, if any
