Procedure/Observations: 1. Weigh out ~280 mg of acetanilide in a 10 mL r.b. flask with a stir bar. 2. Then‚ add 2.0 mL of glacial acetic acid using a calibrated Pasteur pipet. 3. Stir the mixture until all of the acetanilide has dissolved. It may be necessary to add more acetic acid dropwise until full dissolution has occured. 4. In the fume hood‚ add 0.6 mL of 4.1 M bromine solution in acetic acid. 5. Cap the round bottom flask before returning to the bench. 6. For 15-20 minutes‚ stir the reaction mixture

html&session=20120502004843_66.249.71.242&faqview=1 We advise you not to use acetic acid-based descaler (vinegar)‚ as this could have a negative effect on the taste of the coffee. Note: Never use an acid- or vinegar-based descaling agent with 8% or more acetic acid to descale the appliance‚ as this may cause damage. http://www.diynot.com/forums/viewtopic.php?t=30088#axzz2Bph0xR9a Citric acid will do a better job than the acetic acid in vinegar. That’s because calcium citrate dissolves in water whereas

equations. Hypothesis If methyl-2-propanol is reacted with formic acid then the product should be 2-methylpropyl methanoate. If 1-octanol is reacted with acetic acid then the product should be 1-octyl ethanoate. If methanol is reacted with salicylic acid then the product should be methyl salicylate. If 1-pentanol is reacted with acetic acid then the product should be pentyl ethanoate. Materials Equipment 4 test tubes graduated cylinder (10 mL) 150 mL

a variety of other plants such as fennel root. This compound is closely related to apiole‚ having amethoxy group positioned differently on the benzene ring. Vinegar is a liquid consisting mainly of acetic acid (CH3COOH) and water. The acetic acid is produced by the fermentation of ethanol by acetic acid bacteria. Vinegar is now mainly used as a cooking ingredient‚ but historically‚ as the most easily available mild acid‚ it had a great variety of industrial‚

A compound that behaves in this matter is 4-aminophenol and is widespread in the industrial production of this drug. Upon these observations was the build up of “Chemical A” decided. When 4-aminophenol is t treated with acetic anhydrate it produces paracetamol. This procedure is the last stage of an industrial production of the drug called

Determining the precise concentration of vinegar through titration using a standard solution of Potassium Hydroxide (KOH) (aq) Background: Vinegar is a solution of acetic acid (CH3COOH) in water. The concentration of acetic acid in Vinegar is written as a Molarity (mol/L). In this experiment‚ titration is used to determine the concentration of acetic acid in vinegar. Titration is an experimental technique for determining the concentration of a solution by reaction with something else. To perform a titration

Abstract The bromination of trans-cinnamic acid was completed to determine dibromide’s stereochemical structure and its mechanism. After the addition of bromine to trans-cinnamic acid‚ the product was identified by its melting point and infrared spectrum resulting in erythro-2‚3-Dibromo-3-phenylpropanoic acid after comparing similar properties. Introduction In this lab‚ the bromination of trans-cinnamic acid was completed to determine dibromide’s stereochemical structure‚ and from there determine
