Acetic acid

(Zn), iodine (I2), acetone (C3H6O), acetic acid (C2H4O2) and zinc iodide (ZnI2) were used to conduct this experiment in order to confirm the validity of the law of conservation of mass as well as to use Stoichiometry to calculate the reaction between zinc and iodine. There are some precautions that one must consider before handling and using these specific chemicals. All of the chemicals used impose at the minimal, hazard to skin and eyes. However, acetic acid in particular can be very…

grains, molasses, etc. They all have the ability to be fermented. This can be done by using a slow or fast process of fermentation. Yeasts ferment the sugars in the apples into alcohol and then bacteria convert the alcohol into acetic acid in apple cider vinegar. Acetic acid is the main key ingredient in vinegar which creates the bold flavor. It also contains nutrients such as B vitamins and vitamin C. There is a buildup of yeast and bacteria called the mother when you make vinegar using the…

phyto-constituents varied between the plants and also within the plant. The total steroid content was found to be higher in CBE followed by total phenols, flavonoids and ascorbic acid. On the other hand, in CQE steroids are higher in concentration compared to all other phyto-constituents followed by flavonoids, total phenolics and ascorbic acid.…

esters are found in fruits. An ester is a product of the reaction of an acid (carboxylic acid) and an alcohol (the hydrogen of the acid R-COOH is replaced by an alkyl group R'). Esters mainly result from the condensation (a reaction that produces water) of a carboxylic acid and an alcohol. The process is called esterification. This reaction can be catalyzed by the presence of H+ ions. Sulfuric acid, H2SO4, is often used as a catalyst for this…

carboxylic acid for testing. Each group then synthesizes an unknown ester from a Fisher Esterification reaction of the given unknown. Once an ester product is obtained, 1H and 13C NMR, boiling point, and smell testes are run on the final product in order to identify all the given unknowns. Procedures The first step of this week’s lab was to mix 3mL of the unknown alcohol and 6mL of the unknown carboxylic acid in a microwave reaction vessel. To the mixture, 0.75mL of concentrated sulfuric acid…

N-acetyl-p-toluidine, p-acetamidobenzoic acid, and p-aminobenzoic acid, was checked for yield, presence, and purity through weighing, taking IR and NMR spectrums, and determining the melting point. Thin Layer Chromatography was used to ensure the completion of the final reaction from p-aminobenzoic acid to benzocaine. The yield of the first step from p-toluidine to N-acetyl-p-toluidine was 91.9%. The yield of the second step from N-acetyl-p-toluidine to p-acetamidobenzoic acid was 49.85% The…

tetra-n-butyl titanate as the precursor. Solution A was prepared by dissolving 17 mL TBT in 30 mL anhydrous ethanol with stirring (300 rpm) for 30 min. The other solution that contained 28.35 mL anhydrous ethanol, 7.25 mL deionized water and 20 mL 3 M acetic acid was slowly added into the above solution with magnetic stirring at room temperature. The prepared mixture was further hydrolyzed for 60 min with stirring until the transparent sol was obtained, which was aged for 20 h at room…

Khadra Hassan TA: Hannah Degraaf September 28th 2016 Banana Oil (lab report) Purpose: The purpose of this laboratory experiment was to synthesize banana oil (Isopentyl acetate) from the reaction of Acetic acid and Isopentyl alcohol by the Fischer Esterification reaction. By using the methods of refluxing, washing, drying, and simple distillation to purify the end product. When the product was isolated an IR, H NMR and boiling point were used analysis the product, the end product had a…

The purpose of this lab was to synthesize acetanilide and use recrystallization to isolate the acetanilide product from small amounts of impurities, acetic acid. Recrystallization is a very effective way for organic chemists to isolate a solid product from a small amount of impurities but cannot be used for liquids. The crude acetanilide product and the recrystallized acetanilide were compared using melting point determination and the recrystallized product was then classified and checked for…

calculated to get 2.5 g/mL, and its known density was only 0.2 g/mL away. After calculating the density of WC, the results had a 0% error. Also, comparing the physical characteristics of WC to oak, they were relatively very similar. Lastly, through the acetic acid test, and the iodine test, the results matched up to corn starch 's properties. When the iodine test was done on PA, it matched up to the results of corn starch, turning purple and clumping together. China will receive LB, after its…
