Determination of Iron by Reaction with Permanganate-A Redox Titration Purpose: The purpose of this experiment was to find the percentage of iron in an unknown iron oxide sample which could be determined through titration with a standard solution of potassium permanganate. Success in this analysis requires careful preparation and attention to detail. Performing this experiment also provides practice at titrations. The overall reaction is: 8H+(aq) + MnO4-(aq) + 5e- Mn2+(aq) + 4H2O Theory:

Short Essay 3 Propaganda is a useful tool for any politician or government‚ especially in unstable times such as during or after a war. Not surprisingly‚ aspects of propaganda can be found in both Churchill’s "Iron Curtain Speech" and Stalin’s "Response to Churchill". The speeches both contain elements of truth and distortions of that truth‚ and any dissection of them will reflect the author’s cultural and national background. Keeping this in mind will serve to rationalize any conclusions reached

Watching Iron Jawed Angels really opened my eyes. There was struggle between women and politics‚ but also between women themselves. It was not easy to gain these rights. This was just one step in gaining the equality that women should have. As Alice Paul says in the movie‚ “It’s unfair to die in a fight we shouldn’t have to fight.” In Iron Jawed Angels‚ we are shown part of the journey to gain women the right to vote. Alice Paul and Lucy Burns meet with Carrie Chapman Catt and Anna Shaw about being

The purpose of this 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

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
