Consider the following redox reaction which was conducted under acidic medium to answer this question. x2- M3+ XO M+ + + A 0.122 M Na2X (MM = 78.3) aqueous solution was placed in a buret and titrated against a 1.02 g sample of 75.9% pure MCI3 (MM = 57.5) that had been dissolved in an appropriate amount of acid until the redox indicator changed color. Given this information, how mL of titrant were necessary to completely react with the titrand? Use 3 significant figures to report your answer.
