Acetic acid

standardize a sodium hydroxide solution as well as determine the molar concentration in as strong acid and the percent by mass of acetic acid in vinegar. We used volumetric analysis, also known as titration, in both experiments. The average molar concentration for NaOH was 0.2749 mol/L while the average molar concentration of the acid solution was .2493 mol/L.The average percent by mass of acetic acid in vinegar was found to be 12.3 % Introduction: The Purpose of experiment 9 was to prepare and…

the 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…

The experiment goal of the lab is to determine the concentration of acetic acid (CH3CO2H) in the commercial white vinegar brand. Procedure and Data Statement The complete experimental procedure is available in the General Chemistry Laboratory Manual for CSU Bakersfield, CHEM 211, pages 60-61, 64-65. Experimental data recored on the attached data pages 62-63, 66-68. Discussion…

concentrated sulfuric acid in the first step? The purpose of using concentrated sulfuric acid is to activate the reaction of salicylic acid and acetic anhydride and produce the acetylsalicylic acid, which is aspirin. The sulfuric acid is used to protonate oxygen atom of a carbonyl group of salicylic acid. 2. What would happen if the sulfuric acid were left out? Removal of catalytic acid from the reaction would slow down or not proceed at all because the phenol group on salicylic acid is not…

front line with a pencil. Three spot were labeled A, B, and C. A sample of each standard was spotted on the analytical TLC plate approximately 1cm from the bottom of the plate. It was then enclosed in a jar filled with 2ml of 95% ethyl acetate- 5% acetic acid. (Another laboratory group conducted the same procedure but using 1:1 Hexanes: Ethyl Acetate as the developing solvent). After the TLC plate was developed until the solvent reached 1cm at its top; the plates were analyzed using UV light and…

its reaction with vinegar? Aim: To find out how different amounts of baking soda (soda bicarbonate) affect the length of its chemical reaction with vinegar (acetic acid). Hypothesis: If the amount of baking soda is increased then the length of its reaction with vinegar will increase because there will be more soda bicarbonate for the acetic acid to react with. Equipment:  Baking Soda  Vinegar  5 glasses  Safety glasses  Measuring Spoons  Stopwatch  Scale Variables: -Independent…

occurs in the liquid phase according to the radical mechanism produced by MEC as the intermediate and acetic acid as the final product. Mice and acetic acid (0.2: 1.0 mass ratio) are obtained by non-oxidizing liquid phase oxidation at 1800C and 53 bars with remixing. Continuous oxidation under the flow conditions of components at 1500C, 65 bar and the stay time of 2-7 minutes constitute MEK and acetic acid by 3: 1 mass. This process has a slight economic advantage over the removal of 2-butanol.…

The purpose of this lab was to perform the condensation of acetic acid with isopentyl alcohol in the presence of sulfuric acid. Isopentyl acetate was formed from this reaction and this compound has the distinct smell of bananas. This reaction is known as Fisher Esterification. From the final product, the final mass was used to calculate the percent yield. Finally, the IR spectrum was obtained from the final product in order to determine if the reaction went to completion or not. To a 5mL…

2. Experimental 2.1. Materials and reagents Analytical grade bentazon was purchased from Sigma-Aldrich. Acetonitrile, methanol, ethanol, chloroform and acetic acid were purchased from Merck and were analytical or HPLC grade. Methacrylic acid (MAA) as the functional monomer, ethylene glycol dimethacrylate (EDMA) as the cross-linker and α,α′-Azoisobutyronitrile (AIBN) were purchased from Merck (Hohenbrunn, Germany). MAA was distilled under vacuum to remove the inhibitor prior to polymerization.…
