This lab was basically about finding the percentage of acetylsalicylic acid in an aspirin tablet. First, the base was created, which was made out of 1.00 g of NaOH and D-water. Then the buret was attached to the clamp on the ring stand and the base was poured into the buret. After that, one by one, an aspirin tablet was dropped into an Erlenmeyer flask filled with 50 mL of D-water so that it could become dissolved. After the tablet was completely dissolved, a few drops of phenol were added, and the base was added very slowly, changing the color

When the base was mixed with the dissolved aspirin tablets nothing happened. 11. When the drops of phenol were added, then the mixture turned pink. 12. At first, the base was added to quickly so it turned into a dark pink, almost purple. 13. After swiveling the mixture a few times it would lose its pink coloring and turn back into a clear color. 14. At the second try, the base turned into a medium pink color. 15. It stood pink for a longer period of time, approximately 1 minute. 16. The mixtures for all three trials were odorless. 17. At the last try, the base was a light pink color, and it stayed for two minutes. 18. When too much base was added to the phenol/ dissolved aspirin, the mixture would turn into a dark pink. 19. When the base was added in slowly, the pink color lasted a longer time. 20. The faster the base was added, the darker the mixture got, and the longer it took to return to its original clear color.

    aspirin Intro- Aspirin is known as a pain reliever for muscle ache, head ache and can prevent heart attacks as well as blood clots, and many more things that it can help with. Aspirin is known as Acetylsalicylic acid (ASA) is a Salicylate. Salicylates are organic acids from plants that people for hundreds of years have been used for pain reducing. Salicylic acid irritates the stomach when consumed so German scientist Felix Hoffman suggested ASA as an alternative. Aspirin is made when Acetic Anhydride…

    this lab was to synthesize and purify aspirin. The theoretical yield was calculated to 3.766g. The actual yield of pure aspirin was 2.863g with a yield of 76%. The percent yield indicates that our synthesis was a success but the yield is low and indicates that some of the aspirin was lost during synthesis. Some reasons for loss can result from human error such as loosing product from sticking on the spatula and the Buchner funnel and several weighings. Also, when transferring the crude aspirin into…

    Preparation of an Ester Acetylsalicylic Acid (Aspirin) OBJECTIVE: To become familiar with the techniques and principle of esterification. DISCUSSION: Aspirin is a drug widely used as an antipyretic agent (to reduce fever), as an analgesic agent (to reduce pain), and/or as an anti-inflammatory agent (to reduce redness, heat or swelling in tissues). Chemically, aspirin is an ester. Esters are the products of reaction of acids with alcohols, as shown in the following equation using…

    Commercial Aspirin Tablet Analysis Tuesday Evening Intro: The purpose of this lab was to analyze commercial aspirin tablets. To do so, the percent acetylsalicyclic acid (active ingredient) in tablets using acid-base titration was determined, the percent acetylsalicyclic acid in tablets by formation of a colored iron(III)-salicylate complex was determined using spectrometry, and then the percents from each process was compared. Acetylsalicylic acid is produced when salicylic acid and acetic…

The number of moles of the purified aspirin product after extraction was 7.77 x 10-4 as shown in Equation 4. These two moles calculated a chemical yield of 54.3% as shown in Equation 5. The melting point of the pure aspirin product was ranged at 117.8-125.2C as shown in Table 1. An infrared spectrum for the pure aspirin from the synthesis was taken by using crushed crystals…

    IB1 Chemistry Practical #8 ANALYSIS OF ASPIRIN TABLETS For a long time the bark of the willow tree (salix alba) was used as a traditional medicine to relieve the fever symptoms of malaria. In the 1860's chemists showed that the active ingredient in willow bark is salicylic acid (2-hydroxybenzoic acid) and by 1870 salicylic acid was in wide use as a pain killer (analgesic) and fever depressant (antipyretic). However, because it is a relatively strong acid, salicylic acid has the undesirable side effect…

Aspirin were made using a combination of salicylic acid and acetic anhydride.The goal of this experiment was to determined the purity of aspirin using different methods. These methods included, reacting salicylic acid with FeCl3, finding its melting points, and by doing Thin-layer chromatography. When you reacted salicylic acid with FeCl3, changes in color will occur. Pure Aspirin has a melting point around 135°C and a pure salicylic acid…
