and acetic acid affect the amount of carbon dioxide that is produced? Hypothesis: Except when there is not enough acetic acid to react with all of the sodium bicarbonate, the amount of carbon dioxide that is produced will increase proportionally with the amount of sodium bicarbonate that is used. Dependant Variable: The volume of carbon dioxide gas produced by the reaction. Independent Variable: The amount of sodium bicarbonate used in the reaction. Control: The amount of acetic acid used

FDA Vinegar / Acetic Acid Analysis Objective- Determine the Acetic acid level contained within the vinegar sample Background- Per the FDA regulation which states that consumer vinegar may contain no less than four percent and no more than five percent Acetic Acid, we will determine the Acetic Acid content of a sample of the vinegar in question through titration. After standardization of our titrant, which in this case will be NaOH, we will use this along with the indicator Phenolphthalein

acetylation with acetic anhydride.A known weight of the alcohol is acetylated with acetic anhydride in presence of dry pyridine. The amount of acetic anhydride is used in the excess is hydrolysed by water to acetic acid at the end of reaction. Acetic acid so produced is titrated against standard alkali solution to determine the amount of the unreacted acetic anhydride. Reaction: (CHsCO)2 + H2O → 2CH3COOH Reagents: Distilled acetic anhydride, 0.5 N sodium hydroxide, dry pyridine, Acetic anhydride in

Organic Chemistry Lab B Experiment performed on April 30th, 2015 Abstract Purpose The purpose of this experiment was to prepare isoamyl acetate from isoamyl alcohol and glacial acetic acid by Fischer esterification. Introduction Esters are derivatives of carboxylic acids. Instead of having the –COOH group, an ester will include an alkoxy substituent which is a hydrocarbon group of some kind attached to the oxygen molecule (-OR) (1, 2). Esters emit fruity smells and are

Abstract: The purpose of this experiment was to create an ester by adding and alcohol to acetic acid. I added a spin vain, 10 blue beads of silica gel, 800 microliters of isopentyl alcohol, 1.5 mL of glacial acetic acid and then added 4 drops of concentrated sulfuric acid to the reaction vial. Next we properly hooked up the clear tubing that connects to the water faucet and turned the sink on. We let it reflux for 90 minutes and then we quickly cooled it off using the sink water. We then transferred

salicylic acid were measured using an electronic balance. 2. The salicylic acid was then transferred into a 150 mL beaker. 3. Using a 10 mL graduated cylinder, 9.20 mL of acetic anhydride was measured. A watch glass was placed on top of the graduated cylinder to prevent the spread of acetic anhydride fumes. 4. The acetic anhydride was then added to the salicylic acid. This step was performed under a fume hood. 5. Next, 15 drops of 85% phosphoric acid were added to the solution of acetic anhydride

However, the proton that left replenishes that acid catalyst to help repeat the mechanism for other molecules. The general mechanism of Nucleophilic Acyl Substitution could be simplified and shown by Figure 3 and the specific mechanism of the Fischer Esterification reaction that ensues in the experiment

Objective The purpose of this experiment was to use stoichiometry to calculate the volume and percent yield of CO₂ produced from a reaction of acetic acid (vinegar) with baking soda. Procedure First the balloon was weighed on its own, and its mass was 2.8 grams. Then the container with the sample of baking soda was weighed and its mass was 14.0 g. The baking soda was then placed into the balloon and the mass was 6.4 g. Lastly, the container minus the baking soda was weighed in order to

Isopentyl was selected as the reactant alcohol used for synthesis. Acetic acid was used to react with the isopentyl, creating an acid-base reaction. Sulfuric Acid was used as a catalyst to speed up the reaction, allowing the reaction to occur over a shorter period of time. A higher concentration of alcohol was used than the acetic acid because the isopentyl was the limiting reagent. Le Chatelier’s principle states that a higher concentration of reactants causes the equilibrium of the reaction to
