This means that the unknown compound does conduct electricity. The compound was tested and had a pH of 5. This means that the compound is acidic according to the pH scale. Being acidic means that the substance has more hydrogen ions than hydroxide ions according to “pH”3 .The chemical and physical properties are stated in Table 1.…
By placing the nichrome wire in our compounds and putting it into the flame we can analyze the color of the flame to determine which cation is present in our compound. Along with the flame test, came the ammonium test to detect if the cation, ammonium, is present. By adding 1mL of our compound solution and 1mL 6M NaOH, a smell will develop if the ammonium cation is…
Infrared spectroscopy revealed three peaks at frequencies ~1650 cm-1, 3196-3333 cm-1, and 3439 cm-1. Those peaks indicate the presence of an amide, amine, and an alcohol, respectively.…
Discussion and Scientific Explanations The main goals of this experiment was to find the unknown compound, to discover the compounds chemical and physical properties and create two synthesis of the compound and compare the two compounds. We found out our compound was ionic because the compound dissolved in water, but not in toluene or acetone by using a solubility test, results on Table 1 of the group lab report. On page 59 of the Cooperative Chemistry Laboratory Manual is a chart on suggested liquids and the inference if the compound is soluble [1]. When then checked the pH of the solution by using pH strip. The solution had a pH>7.…
The goal of the lab was to identify an unlabeled compound found in the chemistry stockroom to be able to dispose of it properly. This lab demonstrated the process of identifying an unknown compound as well as synthesizing the compound. Identifying the compound consisted of performing various tests to detect the chemical and physical properties of the compound and comparing it to the list of possible compounds. The tests conducted were the solubility test which the compound fully dissolved in water, the flame test which had no discoloration when held in the flame, cation and anion tests which showed the existence of some halides like Cl, Br, and I, pH test in which the compound had a pH of 6, and the conductivity test which had an average value…
Respectively, the known/unknown were reacted with HCl, NaOH, NaCl, CaCO3, and HNO3 and AgNO3. With the results lining up between the known and the unknown, more properties were identified and more evidence for a positive identification. The five reactions that were carried out further validated our conclusion, since the results were the same between the unknown and the known. For the four that did not react with the unknown, nor did they react with the hypothesized compound, validating the conclusion.…
No ammonia smell was formed when conducting the analysis of cations while the flame test created a color comparable to that of a pale violet signifying that the unknown compound contained potassium. Lastly, the anion test for chloride…
Any agent that interferes with enzyme activity is an inhibitor. Inhibitors can affect the catalysis and/or the binding of enzymes to substrate. (McMichael) Malonate is an inhibitor of SDH mainly because of its shape and function. The shape is similar to that of succinate. (Clark, 2009)…
The experimental procedure includes synthesis of dinitrosyliron dicarbonyl complex, coordinating it with 2,3,4,6-tetramethyl-d-glucose-1-tho and 2,3,4,6-tetraacetyl- β-d-glucose-1-thio molecules to improve its stability. The complexes are used as carrier/ transporter of nitric oxide into the cellular organelles. The chemicals sodium nitrite used as NO source and tetrahydrofuran used for coordination of molecules. The glucose molecules and materials required for synthesis were purchased from sigma Aldrich and VWR international.…
The drug Laetrile for Therapy Starting with defining laetrile as stated by Kovacs, it also referred to amygdalin, it is an extract of apricot seed, almond seed, and apples among other kinds of fruits (Kovacs, 2014). In the 1920s dr. Ernst T. Krebs developed a theory that amygdalin would eliminate cancer cells. However, the theory was incompatible with the available biochemical facts and oncology facts. According to Wilson, the first product which was thought to kill the cancer cells was tested in early 1920 through oral ingestion.…
Medicine has evolved greatly, especially in terms of drugs, but one of the basics is aspirin, also referred to as acetylsalicylic acid. There are many different reactions that can be conducted in order to synthesize aspirin. One way being the Fischer esterification, which is a reaction between an alcohol and a carboxylic acid within the presence of a catalyst, synthesizing an ester (Weldegirma, 2014). The catalyst has to be something that will provide the addition of a proton, such as a Lewis acid, in order to provide a more reactive electrophile and speed up the reaction (Fischer Esterification Fischer-Speier Esterification, 2015). Some possibilities for the catalyst are sulfuric acid, tosic acid, and phosphoric acid (James, 2014).…
By combining the unknown compound with an acid, a base, and two salts, its reactivity was determined. Reacting the unknown compound with sulfuric acid (H2SO4) produced no visible reaction (precipitate), although the pH of the resulting solution was very acidic. Combining the unknown compound with sodium hydroxide (NaOH), a strong base, also had no visible reaction. However, the resulting solution was a lot more basic. Reacting the unknown compound with sodium nitrate (NaNO3), a salt, did not have a visible reaction nor did the pH of the resulting solution change.…
It is made when the amine group of 4-aminophenol is acetylated by acetic anhydride to produce paracetamol and the by-product of the reaction, acetic acid. Paracetamol is contains three functional groups; A hydroxyl group (OH), an amide group (HN-CO-R) and an aromatic group (benzene ring).…
Tartrazine Tartrazine is a chemical that contains numerous positive and negative effects. It is a lemon yellow azo dye mainly used as a food coloring. It has no taste, but s commonly used in foods we eat. Tartrazine’s chemical symbol is C16H9N4Na3a2. The molar mass of Tartrazine is 534.3g/mol.…
It must be synthesized using several, sequential chemical reactions. Benzocaine is useful as a mild topical anesthetic that is the active ingredient in many anesthetic ointments such as Orajel for teething relief and Solarcaine, for sunburn relief. The four step synthesis of benzocaine (ethyl 4-aminobenzoate), 6, in this lab would typically result in overall benzocaine yield of 17.9% from the starting material p-toluidine, 1. Sharma and associates synthesized benzocaine beginning from vasicine with is found in the leaves of Adhatoda vasica. Specifically, nitro compounds were mixed with vascine in 120°C water for 24 hours and then purified by column chromatography. The final step involved the replacement of an amide with an amine.…
