    physical properties of the elements that are interacting. As of the experiment, when the copper wire and copper (II) sulfate were put together, no physical change was observed. Moreover, copper is not an active metal and does not react with diluted acids. This leads to the conclusion that no reaction occurred between them.…

    T. Heinze et. al. reported the synthesis of new 6-deoxy-6-pheylethylamino cellulose derivatives with DSamino 0.4-0.6 by nucleophilic displacement of cellulose tosylates (DSTos 0.74 and 1.29) with a racemic mixture of 1-phenylethylamine under homogeneous conditions, in DMF/H2O82, scheme 30. The optical properties of these deoxyamino cellulose derivatives was studied. A regioselective synthesis of 6-amino-6-deoxycellulose, 6-N-sulfonated, and 6-N-carboxymethylated deoxycellulose were…

    1-phenylazo-2-naphtol, also known as Sudan-1. The first is the diazotization reaction in which a diazonium salt is formed from the conversion of primary aromatic amines, such as aniline, to compounds with the nitroso functional group using a nitrous acid, such as HNO2. The diazonium salt was then used as an electrophile in a coupling reaction with an aromatic compound, β-naphthol. Recrystallization was conducted and yielded 0.18 g of a red-orange compound. The percent yield was determined to be…

    Acid Rain is best described as any form of precipitation with high levels of nitric and sulfuric acid. Acid rain or acid deposition is the result of burning of fossil fuels. About two-thirds of SO2 and one-fourth of NOx are released into the air; it comes from electric power generators. These chemicals react would react with water, oxygen, and other substances to form delicate solution of sulfuric and nitric acid to form acidic pollutants. The source of sulphur dioxide comes from volcanoes,…

    In this experiment I will prepare a pure sample of an element (copper) by making a copper solution and then plating it out onto a more active metal. HYPOTHESIS: Because Copper is a more active metal than Iron, I believe the copper solution will plate onto the iron nail. PURPOSE: The purpose of this experiment is to observe reactions between metals depending on which one is more active and observe how to clean pennies, while making a copper solution. RAW MATERIALS: Two plastic cups Clover…

    ABSTRACT: Terpolymer / kaolinite microcomposites were synthesized by 2:2:1 molar ratio of aniline, anthranilic acid and o-phenylenediamine monomers, respectively using various percentages of kaolinite clay via modified in situ oxidative ter-polymerization. The results were confirmed by FT-IR and UV-Vis absorption spectra of terpolymers / kaolinite composites. The thermal behaviour of the terpolymer and composites was studied. Terpolymers / kaolinite composites were thermally more stable than…

    Abstract: The Grignard reaction was successfully accomplished. An amount of 1.20 ml of 2-methyl-2-pentanol was collected, and 9.60% yield was calculated based on the theoretical yield. Despite the low amount of 2-methyl-2-pentanol, its identity was confirmed by comparing the experimental refractive index and infrared spectrum to the literature refractive index and infrared spectrum of 2-methyl-2-pentanol. Statement and purpose The purpose of this experiment is to synthesize a specific alcohol…

    ENVIRONMENTAL ASPECTS OF SULPHURIC ACID PRODUCTION 1. Safety Aspects 1. Basic Safety Aspects due to Physical properties and behaviour of Sulfuric acid. Basically, we know attention is paramount when adding water to a highly concentrated acid and this is the case with sulphuric acid which is highly risky. Sulfuric acid can have serious adverse effects like burns if it contacts the skin. This is due to the dehydrating properties of the acid on organic materials. Also, when the acid is heated…

    • 4 Pages

    Introduction: Many chemical compounds are broken down into two very distinct categories: acidic or basic. Acidic, based on the Bronsted-Lowry Theory, is defined as a proton (H+) donor. An equation exemplifying an acid dissolving in water is: HCl (g) H2O H+ (aq) + Cl- (aq) A base, based on the Bronsted-Lowry Theory, is defined as a proton (H+) acceptor. An equation exemplifying a base dissolving in water: NaOH (s) H2O Na+ (aq) + OH- (aq) Molarity, also known as the concentration…

    rate is magnesium and hydrochloric acid. Initially, it was hypothesized that the reaction with hydrochloric acid would have the fastest reaction rate due to its high acidity observed from the pH scale. From there, the following reactions were based on the pH of the acid involved as well as the concentration of hydrogen ions/atoms within the acid molecule. As a result, it was hypothesized that the sulfuric acid reaction would be the second fastest and the acetic acid reaction would be the…
