A 0.2000-g illegal firework was tested for its KClO3 content. The sample was treated with 50.00 mL of 0.01750 M Fe²+. The excess Fe²+ was back titrated with 14.00 mL of 0.07500 M Ce4+. a. Write the balance redox reaction for the reaction of KClO3 and Fe²+. Write the balanced half reactions. b. Write the balance redox reaction for the reaction of Fe²+ and Ce4+. Write the balanced half reactions. Calculate the percentage of KClO3 in the sample. C.
