to learn how to use salicylic acid to make aspirin. Aspirin is the most widely used over-the-counter drug in the world. The average tablet contains about 325 milligrams of acetylsalicylic acid with an inert binding material such as starch. Aspirin is used to relieve pain‚ reduce inflammation‚ and lower fever. Aspirin originally was derived by boiling the bark of the white willow tree. Although the salicin in willow bark has analgesic properties‚ purified salicylic acid was bitter and irritating when

nucleophile to the carbocation. The experiment was only able to yield 0.504 grams or 5.21% of the theoretical yield of 9.679 grams‚ which is considered as extremely low percent yield. This result could have resulted from various experiment and experimenter errors and other uncontrollable environmental factors. Introduction An alkyl halide or haloalkane is composed of hydrocarbons with a halogen attached to a sp3-hybridized carbon. It resembles an alkane with a halogen attached to it. Halogens are fluorine

Synthesis Conclusion: Conclusion: As we can see‚ the sources show us that during the Enlightenment period money was very important. It shows that during the time people would do merely anything for money‚ even force their children into arranged marriages or‚ as Voltaire suggest satirically‚ sell them as a food source. Parents or even the brides and grooms themselves would arranged marriages for economic gain. This was not always the case. We have learned from She Stoops to Conquer that‚ although

In part A‚ solutions needed in the experiment were prepared‚ and the LabQuest was set up. By adding 100mL 6M HCl to 200mL deionized water‚ 300mL of 2M HCl solution was prepared. Then 150mL 2M NaOH solution was prepared by adding 100mL 3M NaOH to 50mL deionized water. Finally‚ the LabQuest was connected to the temperature probe‚ and set up to collect data every 15 seconds‚ the duration was set to be 180 seconds. In part B‚ three reactions were performed. In reaction 1‚ two Styrofoam cups were stacked

SYNTHESIS OF THE PHARMACEUTICAL ASPIRIN (ACETYLSALICYLIC ACID) AIM: The aim for this experiment was to synthesise a small amount of aspirin with salicylic acid as the starting product and sulphuric acid as the catalyst. The product obtained from this reaction will be impure and will need to be purified. This will be done by recrystallization. We will then record the products’ melting point and calculate the yield in order to determine the degree of purity of the aspirin sample. Diagrammatic scheme
