Synthesis of Aspirin (Acetylsalicylic Acid) Abstract: This experiment is about the synthesis of aspirin under laboratory conditions. Aspirin is prepared by reacting salicylic acid and acetic anhydride; in the presence of sulfuric acid. After fully dissolving the salicylic acid with acetic anhydride‚ the solution is cooled and cold water is then added. Once the crystals form they are then filtered and left to dry out. There mass is measured and recorded then the yield is calculated. Introduction:

involves a winner. There is always a good and bad side and one of them has to come out on top. In these two stories‚ “7th grade” and “The Melting Pot”‚ each have a winner or a resolution to the problem or conflict either an external or an internal. In “Seventh Grade”‚ the type of conflict is internal‚ because of all the sequences happening in Victor’s mind. In “The Melting Pot” the conflict is external because of all the sequences happening between the people of the town. In the story “Seventh Grade”‚ The

Aspirin has been a pain reliever for more than 100 years. Aspirin has been used as a remedy for many illnesses for centuries now and still more things are yet to be identified about aspirin and its uses. It was recently discovered that aspirin can be used to reduce clotting of the platelets in the blood vessels‚ thus reducing the risk of heart attack in humans. Most students in their youthful age were not able to give their heart the maximum care it deserved‚ as a result‚ it leads to heart related

Aspirin analysis Introduction Aspirin‚ which is also known as acetylsalicylic acid. C9H8O4 is the chemical format for Asprin. The chemical structure of aspirin: Aspirin is anti-inflammatory. Aspirin is prepared by chemical synthesis from salicylic acid‚ by acetylation with acetic anhydride. The fact that it is an acid allows us to quantify the amount of aspirin in a solution. We would do this by by using an acid-base titration. Sodium hydroxide (NaOH) will be used In this experiment as the

Preparation of Bromotriphenylmethane Abstract The structure of a major component of star anise oil was derived by analyzing its IR spectroscopy melting point of after oxidation and purification. From the evidence obtained‚ it was concluded that the exact structured should be p-methoxybenzoic acid. Introduction The purpose of this experiment is to determine the structure of the major component of star anise oil. It is already known that this component has a molecular formula C10H12O. This

Explaining what Aspirin is. An aspirin is a medication used as a treatment to those who are suffering from mild conditions‚ such as fever‚ pain‚ and/or inflammation. It’s helpful use is to give aid to those who are suffering from toothaches‚ common colds‚ chest pain‚ headaches‚ and many more symptoms of mild pain‚ fever‚ or inflammation. It is also known to reduce blood clotting. Its scientific name is acetylsalicylic acid (ASA)‚ with it’s chemical formula being C9H8O4‚ and its IUPAC name being 2-acetyloxy

Experiment 7a Name: Date: Title: Purity of Aspirin by Spectrophotometry Aim: i. To measure the absorbance of different volumes of sodium salicylate solutions and aspirin with iron chloride ii. To find the concentration of each standard solutions iii. To determine percentage purity of aspirin. Abstract: The mass of acetylsalicylic acid was determined using a analytical balance. Sodium hydroxide (NaOH) was added to the acetylsalicylic acid and heated in order to hydrolyze acetylsalicylic
