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 %
The Purpose of experiment 9 was to prepare 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).
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.
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 ferric chloride test is used to determine the presence of phenols in a given sample or compound (for instance natural phenols in a plant extract). Enols, hydroxamic acids, oximes, and sulfinic acids give positive results as well. The ferric chloride test can be used to detect metabolites in urine in case of inborn error of metabolism such as phenylketonuria. In addition,the Ferric Chloride test can be used to detect salicylates in urine after an aspirin overdose.1
to a 25-mL round-bottomed flask along with a stir bar. To dissolve the camphene, 3.0 mL of glacial acetic acid was added into the flask. The flask was fastened onto a ring stand and immersed in a water bath that was on top of a stir plate. A thermometer wire was placed in the water bath to monitor the temperature throughout the experiment. After the camphene dissolved, 0.50 mL of 8 M sulfuric acid (H2SO4) was added. To prepare for heating, a cork was placed upside down to cap the mixture and…
experiment tested why mixing reactants in different mole ratios affected the amount of the product and the amount of each reactant that is left over.
To solve the problem, the lab contained reacting sodium bicarbonate(baking soda) and acetic acid(vinegar) in different ratios and seeing if the product changed. The data suggests that the higher ratio of baking soda to vinegar creates the most product. For the ratio 3:1, the final grams of sodium acetate(product) was 0.09, the product…

place. The temperature dropped about 6 degrees Celsius. The remaining solution was a filmy and diluted. The result was sodium acetate dissolved in water. This reaction was a double displacement reaction. The sodium bicarbonate reacted with the acetic acid vinegar and produced sodium acetate, water, and carbon dioxide. The carbon dioxide escaped from the solution leaving water and sodium acetate.…
In the foregoing paper, the author reported that ethyl ester of
highly unsaturated fatty acid freshly obtained from cuttle fish oil showed
quite the same good nutritive effect as oleic acid ester for rat, while the
acid exposed to air was proved to be extremely toxic.
Since it seems to be most plausible that the toxicity is concerned
with the formation of peroxide by autoxidation of unsaturated fatty
acid, the author determined the amount of peroxide. The result proved.
this was just the case,…
