Question:

The KClO ₃ in a 0.1342 g sample of an explosive was determined by reaction with 50.00 mL of 0.09601 M Fe ³⁺:

ClO ₃ ^- + 6Fe ²⁺ + 6H ⁺ -> Cl ^- + 3 H ₂O + 6Fe ³⁺

When the reaction was complete, the excess Fe ²⁺ was back-titrated with 12.99 mL of 0.08362 M Ce ⁴⁺.

Calculate the percentage of KClO ₃ in the sample.
