experiment was to determine the percentage purity of the iron(II) salt in an unknown sample. We performed titrations using Potassium permanganate which is a strong oxidizing agent‚ with unknown sample dissolved in deionized water. The result of the experiment was a 99.5% purity for the anhydrous iron (II) ammonium sulfate. Introduction: In this experiment‚ oxidation/reduction (or redox) will be used in the titration analysis of an iron compound. We will use potassium permanganate‚ KMnO4‚ as

Measurement of Iron in Foods by Atomic Absorption Spectrometry Chem 462 Abstract The purpose of this experiment is to find the amount of Fe in dietary tablets by UV-visible spectrophotometer. A Perkin-Elmer Lambda 6 UV-Visible spectrophotometer will be used for the unknown sample and the iron(II) standards. Introduction Fe3+ in a dietary tablet is converted to Fe2+ and reacats with 1‚10-phenathronile to form the tris(1‚10-phenanthroline) iron (III) complex. Hydroquinone is used as the
