    Redox Titration Lab ABSTRACT: In this lab‚ 0.010 M purple-colored potassium permanganate solution was standardized by redox titration with iron (II) ammonium sulfate hexahydrate (FAS). The average mass of the three flasks of FAS was 0.483 grams. Once the concentration of the standard solution of KMnO4 (aq) was determined‚ it was used to determine the concentration of Fe2+ in iron pills. On average‚ there was 0.01813 L of solution used. With this information and the balanced net-ionic equation
