process where iodine is used as titrant for strong reducing agents. Another type of titration where iodine is involved is called iodometry‚ where iodine “is produced in-situ from the quantitative oxidation of iodide and then subsequently titrated with thiosulfate solution‚”2 being the difference from the former type of iodine titration. Iodometry is more widely used‚ as in this experiment‚ because there are only a few strong reducing agents; thus few iodometric determinations. (2) As mentioned earlier

Period 1 11/7/13 Chapter 35 Discussion Background: Potassium permanaganate is widely used as an oxidizing agent in volumetric analysis. In acid solution‚ MnO4- ion undergoes reduction to Mn2+ this is the equation: 8H+(aq) + Mno4-(aq) + 5e- Mn2+(aq) + 4H2O Since the KMnO4 – ion is violet and the Mn2+ ion is nearly colorless‚ the end point titrations using KMnO4 as the titrant can be taken as the first pink color that appears in the solution (and stays without disappearing).

are they are used to great effect‚ killing thousands and injuring many more. Chemical weapons were first used in combat in May 1915 when the Germans released chlorine gas against the French in the Battle of Ypres. Over the course of WWI new chemical agents were developed including cyanide‚ phosgene and mustard gas. The Geneva Protocol of 1925 condemned chemical weapons but states that if a state used chemical weapons retaliation in kind was acceptable. The treaty also did nothing to stem the production

solution. In the displacement reaction of metals‚ the more electropositive metal will displace the less electropositive metal from its salt solution Through the observations of experiment results‚ aligning them with theory‚ oxidizing and reducing agents are distinguished. DISCUSSION Part A: Metal-Metal Ion Displacement Reactions In the first set experiments involving metal-metal ion displacement metal-nitrate solutions were prepared first. Using the formula: Molarity=moles of solute liters

Impact of The Vietnam War on Society (Aus&VC) The Vietnam War had a lasting effect on Vietnam Vets‚ Who although fought their hardest for their country returned to a country that saw them as murderers and less than heroes. There were no parades for them and they were met with contempt rather than gratitude. Many of the Vietnam veterans suffered from both psychological and medical problems from open battles‚ sniper attacks‚ chemical warfare and just the general stress of war life. Although the Vietnam

Abstract: 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

Toxicological Chemistry - relates the aspects of toxicology to the chemical structure and reactivity of the toxin. It is concerned with the chemical interaction of the toxin with the receptor that gives the physiological response. The ultimate aim is to relate functional group chemistry of both toxin and receptor to the interaction Toxicity - the degree to which a substance causes damage to an organism Acute toxicity - the adverse effects resulting from a single exposure‚ or exposure over
