Experiment 4 Synthesis of Salicylic Acid Introduction Throughout history‚ botanical extracts have been used as medicines. Approximately 30% of all medicines have a plant origin. This number increases to 60% if you consider medicines that at one time were derived from plants‚ but have been synthesized in the laboratory. Salicylic acid is a white crystalline compound that can be isolated from the bark of birch trees. Since it is a valuable substance that can be isolated from nature‚ it is called

Synthesis of benzilic acid from benzoin utilizing a multi-step reaction. Names: Arian Karim TA Name: Sayantan Das Lab Day & Time: Thursday 7:30-11:40 Lab Section #: Abstract The main purpose of this experiment was to synthesize benzilic acid from benzoin. This requires a multistep synthesis with benzyl as an intermediate product. The first step required HNO3 as an oxidizing agent and the second step required KOH and HCl. The percentage yields of benzil and benzilic acid were 59.5%

Experiment 1: Synthesis of Copper Compounds Introduction This experiment involves the synthesis of compounds originating from pure solid copper. By applying solubility rules and the reactive properties of substances‚ many compounds which would otherwise be costly to extract from nature are able to be synthesized in the laboratory. Laboratory synthesized may sometimes be more economical than natural extraction‚ however it poses its own problems with the amount of substance that is actually yielded

Minimum Wage For years there has been disagreement over whether the minimum wage should be raised or not. Some believe that by raising the minimum wage‚ many Americans would be able to rise above the poverty line and have access to their dream. Others disagree saying that raising the minimum wage would only make it more difficult for businesses to pay workers and people would lose incentive to work hard. The only just choice is to raise the minimum wage so that hard working Americans can exceed

Wal-Mart’s Music Censorship Imagine Green Day just came up with a great album that everyone has been raving about. The excited fans decide to head over to the local Wal-Mart to grab an easily accessible copy of this album. Sadly‚ they find that Wal-Mart will not sell the album because Green Day refuses to self-censor their songs‚ which Wal-Mart demands of all artists. Wal-Mart also refuses to stock CDs with parental advisory stickers on them‚ although it should be the consumer’s choice on whether

EXTRACTION Organic Chemistry Laboratory This experiment was conducted in order to compare single and multiple extraction of caffeine from dried tea leaves and to calculate the percentage yield of caffeine for both extraction procedures. The group was assigned to do the multiple extraction. Before the extraction proper‚ the water bath containing the anhydrous sodium carbonate and distilled water was heated. As the sodium carbonate dissolves‚ tea leaves were added in the mixture and allowed to

Loggerheads also modify habitats as a result of their foraging activities. The fragments of hard-shelled organisms that loggerheads consume are either discarded or ingested and later deposited with feces at a different location. By reducing the particle size of the shells‚ loggerhead turtles contribute to nutrient recycling in benthic ecosystems by increasing the rate of shell disintegration. Additionally‚ a foraging behavior called infaunal mining has a significant effect on substrate characteristics

Table 1. An infrared spectrum for the pure aspirin from the synthesis was taken by using crushed crystals‚ Figure 1. This spectrum was shown with different absorption bands corresponded with the functional groups of aspirin which was observed at frequencies > 1500 cm-1. These infrared frequencies were shown in Table 2. An infrared spectrum of an authentic aspirin was used to distinguish how authentic the infrared spectrum from the synthesis was shown in Figure 2 In this lab‚ aspirin was synthesized

Relationships Family and friends play a huge role in a person’s life. They can be the best part of life‚ or the worst part of life. No one gets to choose who is a part of it and how much of an impact they will have. They can either bring you down to the deepest darkest moments in life‚ or can lift you up and influence your life in many ways. No matter what the circumstance are or who is there‚ there will always be people in your life that will affect it. Hamlet‚ who lives with his mother
