Impurity

technological value, not an artistic one.” Smithson attacks the idea of refinement, claiming that refinement hides the processes that “makes one aware of the sub-strata of the Earth”, while stating that impurities in technology are not necessarily bad, because the Earth is also made up of impurities. Smithson criticizes the artist that works “within the limit of his ‘craft’” for attempting to “copy a perfect mental model”, while expressing that the artist who refuses “technological miracles”…

When analysing Hitchcock’s Psycho, it is clear why it has been labelled as a horror. Although Norman Bates is not a monster in the physical form, his monster-like nature is within his human psyche. There are many reasons for this film to be regarded as a “horror”, the imagery of the old dark house is typical of “horror”, being set in an isolated place, off the beaten track presents a clearly gothic setting where as little as the appearance of a single woman unleashes forces of sexual assault,…

Exp D. Post Lab Questions 1. What is the purpose of the 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…

The manufacturing and production industry during the Industrial Revolution had substantially contributed to the creation of the modern society. It marked the beginning of the use of machinery to manufacture products. From machinery to new forms of power, the achievements made during the Industrial Revolution shaped much of the modern world that humans live in today. During the Industrial Revolution, improvements in machines produced larger quantities of manufactured goods, which led to a…

In the beginning, Palestinians didn’t live a so-called “religious life”. It was messy, all over the place, even though mental notes of the Jewish God seemed to be everywhere in life of the first century. It seemed to be that the mood of the religion seemed to change with the wind or seasons for that matter. It also wasn’t like that in just one region, but throughout the whole land that considered and claimed Judaism. The most sacred and restricted food was the pig, which honestly is no surprise…

then isolated through vacuum filtration, resulting in pale yellow-white powder. Next, acetone was used to dissolve the powered. This solution, a slightly cloudy yellow liquid, was then centrifuge, resulting in a clear yellow solution with solid impurities. The purified solution was then heated to remove the acetone. This step caused the product solution to become oily. Again, the solution was scratched, and 1.3331 g of powdery substance formed. Finally, recrystallization was performed, and…

(MgSO4) was added to all three. Aspirin was also isolated to calculate what percent of the aspirin was yielded. The results of the experiment showed successful extraction of all three components. None of the purified extractions showed signs of impurities and matched very close to the standards, in terms of Rf values. The extracted and purified acetaminophen had the exact same Rf value of 0.543 as the standard. The purified aspirin had the same Rf value of 0.782 as the standard. Purified…

Impurities in this experiment can result from incomplete acetylation of aspirin or hydrolysis of the aspirin during the isolation steps. The first test to determine the purity of the sample was to take the mass of the of acetylsalicylic acid product and compare…

beakers, Buchner funnel, 10ml buret, 250ml Erlenmeyer flasks, coconut oil sample, filter paper, 100ml graduated cylinder, volumetric pipette, side-arm flask, hot plate and Analytical balance. First, filter the oil sample using filter paper to remove impurities. Next, weigh 5g of coconut oil into 250ml Erlenmeyer flask. Then, add 100ml of neutralized ethanol and 2ml of phenolphthalein indicator. After that, shake until the mixture is completely dissolved. Titrate with standard base 0.1N NaOH,…
