Tripoli Campus Chem 200 Lab Report Experiment 6 : Redox titration Course Instructor: Dr Lisa Diab 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

Oxidation of a Secondary Alcohol Using Hypochlorite October 8‚ 2013 Jennifer Karigan CHEM 2081-004 Jonathon Musila Introduction The purpose of the experiment was to oxidize and identify an unknown alcohol using hypochlorite‚ or household bleach. During the experiment‚ the bleach oxidized the secondary unknown alcohol into a liquid ketone which was distilled or boiled to find the boiling point and then identified using a chart of unknown identities

is a molecule that inhibits the oxidation of other molecules. * Oxidation is a chemical reaction that transfers electrons or hydrogen from a substance to an oxidizing agent. Oxidation reactions can produce free radicals. * These radicals can start chain reactions. *When the chain reaction occurs in a cell‚ it can cause damage or death to the cell. * Antioxidants terminate these chain reactions by removing free radical intermediates‚ and inhibit other oxidation reactions. * They do this by being

has a four number name. The enzyme for this reaction is malate dehydrogenase (MDH). Its enzyme commission number is 1.1.1.37. The first number is in reference to its class. In the case of MDH‚ it is a oxidoreductase meaning that it carries out oxidation-reduction

The oxidation state of the metal is shown as superscripted Roman numerals‚ whereas the charge of the entire complex is shown by the angle symbol together with the magnitude and sign of the net charge. Monatomic ions are sometimes also denoted with Roman numerals; for example‚ the Fe2+ example seen above is occasionally referred to as Fe(II) or FeII. The Roman numeral designates the formal oxidation state of an element‚ whereas the superscripted numerals

acid is benzoic acid( benzene carboxylic acid) which has a benzene connected to the carboxyl carboxyl group‚ -COOH group. It has a formula of C6H5COOH. The carbon atom of a carboxyl group has a high oxidation state. Therefore‚ that many of the chemical reactions used for their preparation are oxidations. In this experiment‚ an aromatic carboxylic acids namely benzoic acid will be prepared by oxidizing benzyl alcohol which is a primary alcohol. The oxidizing agent used is alkaline potassium permanganate

is expensive. The chemical kinetics of gas phase oxidation of ethanol has been reported over last five decades. Data have been reported from nonflow reactors‚ flow reactors‚ diffusion flames‚ and laminar premixed flames experiments by several researchers [2-5]. Detailed chemical kinetics models to describe the gas-phase oxidation of ethanol in air are available in literature [6]. Apart from that a global single step mechanism for ethanol oxidation is also available [7]. Experimental studies have

contains catalysts‚ which are called enzymes. These accelerate the reaction of biochemical reactions in the human body. In a catalytic converter‚ there are two types of catalysts inside. The first one is the reduction catalyst and the other is the oxidation catalyst. Both of the catalysts consist of a ceramic structure. The reduction catalyst is the first step of the catalytic converter. It uses platinum and rhodium to reduce the NOx emissions.

passive diffusion (Rebouche‚ 2006). However‚ in tissues that rely on fatty acid oxidation‚carrier-mediated transport ensures high tissue-to-plasma concentration ratio. One author‚ Rebouche (2006) suggested that L-carnitine dissemination can be either into the muscle or into the liver‚ kidney and other tissue. According to Rigault et al. (2007)‚ L- carnitine is transferred to organs which metabolisms rely on fatty acid oxidation‚ particularly the heart and skeletal muscle. Oxidative stress weakens mitochondrial
