Concentration of Acetic Acid in Vinegar Nalebra Barnett, AAHCA, BSHA University of Central Oklahoma General Chemistry II Lab March 28, 2017 Dr. Lane Whitesell Lab 12. Concentration of Acetic Acid in Vinegar. This laboratory is to determine the concentration of acetic acid in vinegar using molarity and percent by mass of acetic acid in vinegar. This means, vinegar is a crucial solution of acetic acid (HC2H302) in water. Molarity (in mole/L), or mass percent expressed the…

proteins work because they are essential to our health. Without proteins our bodies would not be able to form vital bodily components such as enzymes, and antibodies. A protein is defined as “large molecules consisting of one or more chains of amino acids in a certain order, determined by the base sequence of nucleotides in the base sequence of nucleotides in the DNA coding for the protein” (Medicine net). Insulins formula is C254H377N65O75S6 and its molecular mass is 5808 Da. When the protein…

bottle rocket to go farther. Chemical Reaction Vinegar is an acetic acid. When an acetic acid and baking soda (sodium bicarbonate) are mixed together, three new chemicals are formed, Water (H2O), carbon dioxide (co2), and sodium acetate (C2H3Na02). When one of the three chemical atoms breaks off, it creates the chemical reaction. Vinegar Vinegar is an acetic acid, which is produced by the fermentation of ethanol by acetic acid bacteria (Google.com/vinegar). For the purpose of the experiment,…

Effect of Acid Rain on Wisconsin Fast Plants Introduction Acid rain has become a large environmental problem around the world. This chemically potent precipitation is incredibly common in large metropolitan cities where pollution and smog are prevalent. Acid rain has been known to diminish plant growth or completely kill off populations within the contracted areas of these large cities. In addition to effecting plants, it has also been determined that the pollutants in acid rain, such as heavy…

Aim 2: How does folliculin detect amino acids to regulate mTORC1 activity? Here, the goals are to elucidate the mechanism of action that enables folliculin to function as an amino acid sensor. 2.1. Determine the amino acid reservoir folliculin senses. Evidence points FLCN as a novel amino acid sensor. To resolve the biochemical mechanism FLCN employs, we need identify the specific amino acid reservoir FLCN senses. Lysosomes’ are the main amino acid reservoir and the ‘inside-out’ mechanism is a…

Alkalinity is a measure of the ability of a water to resist changes in pH. Alkalinity in water is due to the presence of weak acid systems that consume by hydrogen ion produced by other reactions, allowing chemical or biological activities to take place within a water without changing the pH (1). In this way the alkalinity protects aquatic life. The measured value may vary considerably with the end-point pH used. Alkalinity is a measure of an aggregate property of water and can be interpreted…

order to convert a carboxylic acid into an ester. As a result of this reaction, the alcohol (-OH) of the original carboxylic acid, Benzoic Acid, will be replaced with the –OCH3 group attached to the original alcohol, methanol. This would then generate the ester, Methyl Benzoate. An ester is a derivative of a carboxylic acid that can be formed in multiple ways. The most straightforward approach to producing and ester involves the interaction between a carboxylic acid and an alcohol, where the…

The benzoin is oxidized with nitric acid to produce benzyl. When benzoin was reacted with nitric acid, an orange color appeared. When was heated the mixture a strong red color appeared in the reflux condenser, which is the visible liberation of nitrogen oxide gases. A total of 0.10 grams of purified benzil was produced from this reaction which contained a detected melting point of 82°C and a 34 % yield. This seemed to be approximately 10 degrees less than the ideal melting point of 94°C, which…

Identifying Unknown Esters Produced by Fischer Esterification Introduction This procedure was performed in order to prepare an ester using an unknown alcohol and unknown acid via Fischer Esterification. Then to identify this unknown ester using gas chromatography. Esters are a derivative of carboxylic acids. In the Fischer approach, an acid is used in order to allow the esterification to occur. Gas chromatography separates compounds by their elution time. Data and Results The compound in the…

leading to strongly improved cohesive properties and stability of drug delivery systems such as matrix systems. Due to the formation of strong covalent bonds with mucus glycoproteins, thiomers show the strongest mucoadhesive properties. Thiolated polymers includes, • Chitosan–iminothiolane, Chitosan–thioglycolic acid • Poly(acrylic acid)–cysteine, poly(acrylic acid)–homocysteine etc 20 Bioadhesive nanopolymers as drug…
