Purpose ! ! ! To review oxidation-reduction reactions and their stoichiometry. To learn the concept and technique of redox titration. To determine the percent (m/v) of an active ingredient‚ sodium hypochlorite (NaOCl)‚ in a commercial bleaching agent. B. Theoretical Background Whereas acid-base reactions involve the transfer of a proton‚ oxidation-reduction or redox reactions involve the transfer of electrons from one substance to another‚ resulting in changes in oxidation numbers of two

April 2005 Identify and elaborate upon the duties that a principal owes to an agent. Answer: An agency is the creation of a contract entered into by mutual consent between a principal and an agent. By agency‚ a principal grants authority to an agent to act on behalf of and under the control of the principal. A principal owes certain contractual duties to his/her agent by an agent will serve the principal loyally and with obedient. The principal duties can

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).

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

Student Name: Marwa Noaman ID: 51230262 Introduction: To determine a substance analytically‚ oxidation- reduction reactions are used. During any redox reaction transferring of reactions occurs from a reducing agent to an oxidizing agent. Purpose: * To titrate "Mohr’s salt" solution with KMNO4‚(second standard) which has to be standardize with oxalic acid (first standard). * To learn how acid-base reactions could be used in titration analyses of unknown substances

It was given its name from the color of the orange-striped barrels in which it was shipped. The government of Vietnam says that four million of their citizens were exposed to Agent Orange. Three million have suffered diseases. This includes the children exposed. The exposure causes many diseases and genetic mutations. How does Agent Orange tie into the

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
