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 reacting with Salicylic acid to produce Acetylsalicylic acid and Acetic acid (diluted vinegar). Aspirin is in millions of home today and in America, about 50 million tablets are consumed every day. When aspirin ages it breaks down and returns to the main chemicals that made the reaction.

Synthesis (procedure)-
for the procedure I prepared a boiling bath using a hot plate, and filled a 400ml beaker with tap water. Then I got a 125ml Erlenmeyer flask and put in 2.00 grams of Salicylic acid using a scale. For the third step I added 5ml of Acetic Anhydride using a graduated cylinder. Then I added 5 drops of concentrated Sulfuric acid to the Acetic Anhydride and Salicylic acid in the Erlenmeyer flask using a dropper. I then heated the flask in the boiling bath for exactly 10 minutes. I then removed the flask and allowed it to cool on the counter for 4.5 minutes while adding 2 ml of cold distilled water dropwise. I then stirred to mix the contents. I Then added 40ml of distilled water in the solution and stirred until crystals began to form. My crystals formed in a matter of seconds. I then put the flask in a 400ml beaker of ice water to cool it down from room temperature for exactly 10 minutes to complete the crystallization process. I then collected the product in a filtration process by using filter paper and washing out the flask with distilled...
