It is somewhat ironic to discover that the pharmacophore of phosphoramide drugs currently used as antitumor agents was originally utilized for the purpose of chemical warfare‚ most prominently so in World War I. Sulfur mustard‚ the precursor to phosphoramide drugs‚ was employed to great effect as a wounding agent in the characteristic trench warfare of WWI; Being a dense gas‚ sulfur mustard settled in trenches and created persistent environmental hazards for troops. Exposure to sulfur mustard‚

Bleach Oxidation of 9-Hydroxyfluorene The purpose of this experiment was to oxidize an alcohol (9-hydroxyfluorene) to a ketone (9-fluorenone) using aqueous sodium hypochlorite (bleach) as the oxidizing agent‚ while introducing techniques used in microscale experiments. Reaction: Results 1. Recrystallized Product Yield Product yield = (actual yield/theoretical yield) x 100% 3mL 9-hydroxyfluorene x (1mL/1000mL) x (0.09 mol/L) = 2.7 x 10-4 moles 0.05g 9-fluorenone / (180.20g/mol) = 2.77 x 10-4

(Harris‚2009). It involves the transfer of electrons between the two solutions. This experiment aims to determine the amount of iron or iron content of a razor blade by redox titration using potassium permanganate as a titrant and a self-indicating agent. Blank titration is used to estimate the titration error. Proper techniques and calculation regarding blank titration is also shown. This experiment will help the students to learn the proper conduction of redox titration and how to apply it in

The Impact of the Vietnam War On Vietnam Veterans and their Families And the Impact of the Australian Culture The Vietnam War had a lasting impact on Vietnam Veterans‚ who although they fought their hardest for their country‚ they returned to a country who saw them as less than heroes. They suffered both psychological and medical problems from open battles‚ sniper attacks and chemical warfare‚ and stress from war-life. Although the Vietnam War had some negative impacts‚ the Vietnam War was the turning

5 Fe+³ + 4H2O (3) Potassium permanganate is widely used as an oxidizing agent in volumetric analysis.Since the MnO4 ion is a deep pink-violet colour and the Mn2+ ion is nearly colourless‚ the end point in titrations using KMnO4 can be taken as the first pink colour that persists in the solution. In titration ‚ permanganate solution is put in the burette and is run down to an acidified solution of reducing agent‚ e.g..ammonium iron(II) sulphate solution.In this experiment‚ KMnO4 will be used

moderately strong oxidizing agent making it useful for titrating strong reducing agents like dissolved oxygen. Iodide ion‚ on the other hand‚ is a weak reducing agent‚ and is the basis of determining the amount of the strong oxidizing agents like the oxygen in the sample pond water. This is done by determining the amount of I3 produced‚ which is equivalent to the dissolved oxygen using titration with thiosulfate. Thiosulfate may be oxidized by strong oxidation agents or form complexes with some‚
