Design Lab Experiment Question: In oxidation-reduction reactions‚ or redox reactions‚ are strengths of reducing and oxidizing agents different from each reaction? Theory of an experiment: 1. Determine the relative strengths of oxidizing agents and reducing agents. 2. Study some simple oxidation-reduction reactions Hypothesis: Relative strengths of reducing and oxidizing agents differ from each reaction. Background Information: Whenever electrons are lost by one substance‚ they must be gained by

chemicals that have been used as chemical weapons‚ or have been developed for use as chemical weapons‚ can be categorised as choking‚ blister‚ blood‚ or nerve agents. The most well known agents are as follows: choking agents—chlorine and phosgene‚ blister agents (or vesicants)—mustard and lewisite‚ blood agents—hydrogen cyanide‚ nerve agents—sarin‚ soman‚ VX. Bombs‚ missiles‚ and other munitions achieve very similar results‚ especially when dropped on civilian areas. But chemical weapons evoke a

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

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‚

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

agriculture; to help rid of insects and help aid disease control. DDT was exiled after the “Environmental Protection Agency” found out these chemicals were going to be toxic to society. Monsanto was also one of very few companies to produce the defoliant “Agent Orange” during the Vietnam War causing over 900‚000 deaths‚ disabilities and birth defects. In total‚ over 4.8 million Vietnamese were exposed to this highly lethal chemical‚ as well as 20 percent of the Southern Vietnamese jungle over nine

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
