The concentration of an aqueous solution of NaOCl can be determined by a redox titration with iodide ion in an acidic solution: Oct +21- +2H+ + Ct +I + Assume that the concentration of iodide ions in the burette is 0.12 M and the volume of iodide solution in the burette and the volume of solution taken in the flask are identical. Correct combination of the concentration of NaOCl and the volume of iodide solution to be added to completely reduce it is/are
