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

numerals and charge notatios for the uranyl ion. 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 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

Oxidation of Borneol to Camphor Objectives: The purpose of this experiment was to use oxidation to convert (1S)-(-)-borneol into (1S)-(-)-camphor‚ which was done via the use of reagents such as glacial acetic acid and sodium hypochlorite and laboratory techniques learned in previous labs. Afterward‚ the final desired product was obtained‚ and to characterize and ensure the purity of the product‚ further lab techniques were implemented. Overall Reaction: 0 out of 10 Oxidation Reaction:. Mechanism:

High intensity interval training (HIIT) is a new popular method of exercising that optimizes your workout by completing a series of short‚ high intensity exercise (90% of your maximum heart rate =220-age).‚ followed by longer‚ lower-intensity exercise (55 to 70 % of your maximum heart rate=220-age). High intensity interval training is said to be significantly more beneficial than other forms of cardiovascular workouts because it challenges the body differently and is more extreme then a moderate

The Nitrogen Cycle Nitrogen fixation Atmospheric nitrogen must be processed‚ or "fixed" to be used by plants. Some fixation occurs in lightning strikes‚ but most fixation is done by free-living or symbiotic bacteria. These bacteria have an enzyme that combines gaseous nitrogen with hydrogen to produce ammonia‚ which is then further converted by the bacteria to make their own organic compounds. Conversion of N2 The conversion of nitrogen (N2) from the atmosphere into a form readily available

Constance Whitney Warren’s bronze sculpture entitled‚ Equestrian Portrait of Diego Velazquez 1924 is located between the General Academic Building and the Physics Building at the University of North Texas Denton Campus. Gift of the Harlan crow family in 1994 but the reasons remain in mistery. The composition of the ten foot bronze sculpture was created inspired by the American West and specializing in bronze equestrian statues‚ portrays the famous Spanish painter Diego Velazquez who is riding a horse
