2. Dilute HCl and 10.00 ml of 0.05000 M KIO3 solution were added to 25.00 ml of KI solution. The released I2 was distilled off, excess KI was added to the cooled solution, which reacted with the remaining KIO3. 21.14 ml of 0.1008 M Na2S2O3 were used for titration of the released I2. Calculate the molar concentration of the initial KI solution.
