Problem- A 5.00 gram sample of iron was dissolved in acid to produce a solution containing Fe2+. The solution was then titrated under acidic conditions to the end point with 45.45 mL of 0.3200 M KMnO4. (The MnO4 was converted to Mn2+). A. Derive the balanced titration equation. B. Calculate how many grams of Fe were in the original iron wire sample?
