INTRODUCTION This purpose of this lab was to prepare aspirin using its basic components: salicylic acid and acetic anhydride. Salicylic acid and acetic anhydride‚ along with an acid catalyst‚ react to form acetylsalicylic acid (aspirin) and acetic acid. In this reaction‚ the hydroxyl group

Abstract Finding the melting point of an organic substance is a practical and efficient way for scientists to identify an unknown substance or determine a known substance’s level of purity. When organic substances are mixed together in varying degrees they take on a melting characteristic that is lower and broader than in its pure form. This property was manipulated in the lab to observe the various melting points of Naphthalene and Biphenyl when the percentage of composition was altered. A

If college athletes get paid it could potentially take away from the purity of the game. Some of the college athletes aren’t as smart so somebody could bribe them to potentially throw a game. And if they get paid they might not play a hard as they could because they might not want to get hurt or injured. Also because they

The American flag is one of our most precious pieces of history. We wave it high in the sky to show that our freedom will never die and we will always fight for it‚no matter how violent or how dangerous that journey shall be. The American flag has gone through many phases and changes. It first stared back in 1775‚ when the American ships in New England flew a white flag with a green pine tree and a saying - "An appeal to heaven." Along with the serpent‚ the 13 stars and 76 stars-our flag finally

objective was to convert a specific amount of salicylic acid into the same amount of aspirin that was high in purity. Furthermore‚ the other objectives were to enable students to conduct the synthesis of aspirin‚ reinforce skills or recrystallisation and the technique of melting point determination. The amount of each compound should be the same because there is a 1:1 ratio between them. The purity of the synthesized aspirin was measured by determining its melting point and percent yield.

Aspirin Background Aspirin Aspirin‚ or acetylsalicylic acid (ASA) is a salicylate drug‚ and is generally used as an analgesic (something that relieves pain without producing anaesthesia or loss of consciousness) for minor aches and pains‚ to reduce fever (an antipyretic)‚ and also as an anti-inflammatory drug.
