13‚ 2013 Saftee Acid In order to complete a shoulder mount for a taxidermy animal the hide must go through several processes. First of which involves removing all of the flesh from the hide‚ once this is complete the hide goes into a solution known as the pickling processes. Once to this stage there are several products that may be used in order to complete a pickled fur. There are three main components to creating a pickling solution; these consist of sulfuric acid‚ non-iodized salt‚

phosphoric acid‚ and 1mL of concentrated sulfuric acid was added to a 250 mL round bottom flask and mixed thoroughly with a magnetic stirrer. A simple distillation set up was installed with a 250mL round bottom flask‚ jack‚ stirrer‚ heating mantle‚ and variac. The solution was heated gently with a small heating mantle to distill the crude product while keeping the vapor temperature around 100C or less. The crude product was collected which contained water‚ 4-methylcyclohexene‚ and trace acid. D

Acid Rain Webquest Name: ________Jacob Rough_________________________ Date: _____3/25/13________ Sulfur dioxide and nitrogen oxides are gases released by the burning of fossil fuels. These gases can react with water and oxygen to form acids. Normally‚ rainwater is slightly acidic. But the additional acid that enters the air when fuels are burned makes it even more acidic. Acid rain can have a harmful effect on fish and other wildlife and upsets the delicate balance

Carboxylic acids are compounds which contain a carboxyl group‚ -COOH group‚ where the -COOH group is attached either to a hydrogen atom or to an alkyl group. One of the example of carboxylic 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

Introduction to Acids Base chemistry Purpose How to determine the constant equilibrium of an acid‚ Ka? How to evaluate the concentration (M) of an acid? In “part A” experiment‚ we would test the PH of different concentration of acetic acid (a weak acid which partially dissociated in water) with a PH probe. After we got the PH‚ we could find out the concentration of H+ by applying the relationship pH = -log [H+]. Having the determined value of [H+] of a weak acid with a known molar concentration

Acid-Base Titration Background Information A titration is a controlled addition of one substance into another substance. In an acid-base titration‚ the experimenter will add a base of known concentration to an acid of unknown concentration (or vice-versa). The goal of the titration is usually to use the substance of known concentration to determine the concentration of the other substance. In order to run a titration‚ the following materials are needed: • A buret filled with the base (or acid) of

Lab Report Acids and Alkalis: Chemistry of Neutralization and Salt Formation Introduction: An acid is a group of chemicals. Acids are positively charged ions‚ they are liquid and are solutions of pure compounds in water. If you want to know if something is an acid‚ you can test it by using litmus paper. Acids will turn litmus paper red‚ whilst alkalis will turn it blue. Alkalis are negatively charged ions and are usually solid. Aim: To find out how much of different acids is needed to neutralize

Amino acids are the building blocks of proteins. They band together in chains to form the stuff from which your life is born. Think of amino acids as Legos for your life. It’s a two-step process: Amino acids get together and form peptides or polypeptides. It is from these groupings that proteins are made. And there’s not just one kind of amino acid. A total of 20 different kinds of amino acids form proteins. The kinds of amino acids determine the shape of the proteins formed. Commonly recognized
