Question 6 : 20.0 mL aliquots of a 0.188 mol/L Fe2*(aq) solution was used to standardize an acidified potassium dichromate solution. The average volume of titrant used in the standardization was 27.62 mL. The acidified potassium dichromate solution was then used to titrate 25.0 mL aliquots of a solution containing l'(aq). An average volume of titrant used in this second series of titrations was 42.86 mL. What is the molar concentration of the I"(aq) solution?
