Benzoic acid

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…

Background: Acidic rain or acid deposition is predominantly caused by air pollution. Acid deposition in the form of gasses and microscopic particles, floating in the air, is called dry deposition. However, wet deposition is in the form of precipitation. As a result of chemicals being released from human productions, great amounts of sulfur dioxide and nitrogen dioxide are respired into the atmosphere, where rain and gas matter is polluted. Once both sulfur dioxide and nitrogen dioxide come in…

recorded. Each Alka Seltzer contains the same three ingredients: 325 mg of Aspirin, 1000 mg of Citric Acid, and 1916 mg of Sodium Bicarbonate. Two of Alka Seltzer’s ingredients, Citric Acid and Sodium Bicarbonate (Baking Soda), were both placed into a beaker to see if both contents could cause a potential reaction. The final result was a non- occurring reaction. For a second test, both the Citric Acid and Sodium Bicarbonate were placed into separate, dry beakers. Afterwards,…

Background This experiment was performed to determine the identity of an unknown organic liquid using physical constants: physical state, color, and odor, the solubility classification: water soluble or insoluble, the results of characterization tests: Lucas test, 2,4-Dinitrophenylhydrazine test, Bromine in Methylene Chloride test, and Ferric hydroxamate test, and analyses of spectral data: IR spectrum and HNMR . All testing samples were added to testing tubes for observation. Data was…

Introduction: The purpose of the experiment was to determine the density of powdered grape. The company Gatorade has advertised that G2 powder replenishes fluids and electrolytes in the body’s blood stream during exercise. G2 has aided in staying hydrated, “maintain normal muscle performance, heart rate and brain activity” (1). In relation, there has been a rise in sports drink purchase to improve athletic performance. The experiment examined a basic level of G2 powders composition, the…

The purpose of this lab is to calculate the chemical formula of a hydrate compound made up of copper, chlorine, and water molecules by using the law of definite proportions. The water of hydration of the copper chloride hydrate sample will be determined as well as the mass of copper and chlorine through a chemical reaction. The results will be used to calculate the moles of copper and chlorine and then the empirical formula of the compound. Techniques used: In this experiment, different…

as: color changes, precipitates, and gases. Those that did not have reactions were also useful in the deduction process. To fully understand how this elimination process works, one must have a better conceptual understanding of aqueous solutions, acid-base reactions, precipitates, and the solubility rules. An aqueous solution is any solution in which water is the solvent. Simply put, it dissolves in water. In order for a substance to dissolve in water, it must either match or exceed the…

Key concepts Chemistry Chemical reaction Acids Bases Water Introduction Have you ever had a refreshing bath with bubbles or bath salts? What if you could use chemistry to create a bath-time treat that incorporated both fizzing bubbles and soothing salts? Such a combination does exist, and it's called a bath bomb. If you have never experienced one, these "bombs" become fizzy when they touch the water. Why? It is due to a chemical reaction taking place between different ingredients within the…

In our Chemistry class, we the students had performed an experiment that involves with a soda can, being crushed. Going step by step, our group simply placed small amounts of water into the soda can. Then we placed the soda can on a hot surface which allowed the water to boil. Once the water was boiling, our group witnessed the steam coming out from the opening on top of the soda can and one of us picked up the soda can with beaker tongs. We quickly submerged it into cold water and the instant…

Table 1 provides the statistics for the first part of lab 11. In this section we used a 1:5 dilution of AdhP from our elution two. Using a spectrophotometer set to 280nm, the concentration of this dilution was found to be 0.08725uM and would be mixed with the various amounts of EtOH and NAD+. When mixed we were then allowed to observe the kinetics using spectroscopy set at 340nm. The data can be seen in Table 1 and Table 2. We were the able to plot this data using Excel thus creating Figures 1…
