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

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

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

Oxidation of an Alcohol: Oxidizing Methoxybenzyl Alcohol to Methoxybenzaldehyde Using Phase-Transfer Catalysis PURPOSE OF THE EXPERIMENT Oxidize methoxybenzyl alcohol to methoxybenzaldehyde‚ using sodium hypochlorite as the oxidizing agent and tetrabutylammonium hydrogen sulfate as the phase-transfer catalyst. Monitor the progress of the reaction by thin-layer chromatography. BACKGROUND REQUIRED You should be familiar with extraction‚ evaporation‚ and thin-layer chromatography techniques

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

real estate happens when a home’s listing agent also represents the buyer in the same transaction. In certain states‚ dual agency is allowed as long as it’s disclosed and with the written consent of both buyers and sellers. Dual agency can occur with the involvement of a single agent or two agents. In a single agent scenario‚ a single agent acts as both the listing and buying agent. In a two agent scenario‚ both the buying agent and the listing agent are licensed under the same real estate broker
