Aspirin Aspirin is a white crystalline substance made of carbon, hydrogen, and oxygen. It is used in the treatment of rheumatic fever, headaches, neuralgia, colds, and arthritis; reduce temperature and pain. The formula for aspirin is CH3CO2C6H4CO2H. Aspirin's scientific name is actylsalicylic acid (ASA). The main ingredient in ASA is salicylic acid. This ingredient grows in small roots, leaves, flowers and fruits on plants. About 100 years ago, a German chemist, Felix Hoffmann, set out
Aspirin (acetylsalicylic acid) is a type of acid categorized as a salicylate, this acid works as a pain reliever in the body because once digested it lowers the amount of substances already in the body that cause pains, fevers and flare ups. Also, this chemical is administered to people for prevention of heart attacks, strokes, and angina which is also known as severe chest pains. Aspirin is created by chemically synthesizing salicylic acid through the acetylation with acetic anhydride, synthesizing
Aspirin is one of the most commonly used drugs in history. Aspirin is used for many different reasons. People use Aspirin for its cardiovascular blood thinning properties, for its pain relieving properties and for it antipyretic properties, to name a few. Most people don’t know what Aspirin is, but only what it does for their particular needs. I will attempt to describe some different aspects of Aspirin and Aspirin overdose. I will give a brief description of what Aspirin is, chemically speaking
4/1/14 Aspirin: Healthy or Not? Whenever pain or a headache is felt people will immediately reach for the bottle of Aspirin they have in their medicine cabinet. For many years this has been the solution to any pain a person feels. As much as Aspirin will help to cure symptoms of pain it may also being doing the body harm. More and more studies have brought many harmful side effects to the surface. The question now comes into play of if Aspirin is actually doing more harm than good. Aspirin contains
Creating and Testing Aspirin Introduction Aspirin is created when salicylic acid and acetic anhydride react together (French et al. 82). However, phosphoric acid is needed as a catalyst, and acetic acid is released as a by-product (French et al. 82). The reaction of aspirin is as shown below: Figure 1. Structures Found in Aspirin Synthesis (French et al. 82 The limiting reagent controls how much product can be produced (French et al. 83). The reagent that is the first to be completely used is the
Synthesis and Characterization of Aspirin Product Identity and Purity After synthesizing a chemical, especially a drug, it is important to confirm the identity and purity of the product. You will perform three tests to examine the identity and purity of the aspirin that you synthesized. One test will detect the presence of leftover salicylic acid in the synthesized aspirin and allow you to determine its concentration. Government regulations stipulate that commercial aspirin must not contain residual salicylic
salicylic acid and aspirin belong to a family of medicinally useful compounds called salicylates. The hydroxyl group present on the salicylic acid is corrosive. As a result, salicylic acid cannot be easily ingested. This property is present in many other compounds that have free phenolic groups. Therefore, an acetyl group, is added to salicylic acid to create acetylsalicylic acid (ASA). So
Introduction Aspirin is one of the most commonly used drug in the world. The generic name is acetyl salicylic acid and the drug belongs to the group of non- steroidal anti-inflammatory medicines, which works by inhibiting the production of compounds in the body that cause pain, fever, inflammation, and blood clots (Koester, 1993. Aspirin is also a member of the salicylate family of compounds as it synthetized from salicylic acid, which was discovered in oxford (UK) by Edward stone in 1793 and first
Discussion 19 The purpose of this experiment was to synthesize and purify of Aspirin and Oil in wintergreen. While determining the purity through analytical techniques. During the first part of the lab the crude sample of acetylsalicylic acid, Aspirin, was synthesized. The synthesis of Aspirin shows a general trend of chemical reactions known as esterification reactions. The compound containing a hydroxyl group reacts with a compound containing a carboxylic acid group, producing an ester molecule
Experimental Overview: In this experiment, I was making a sample of aspirin and then testing it in order to see how pure the sample of aspirin was. By doing this experiment, I was leaning how to crystalize products, and then used the theoretical yield, along with the percentage yield in order to calculate the amount of aspirin that I had created in the sample. Aspirin is an anti-inflammatory, and analgesic, meaning this medication can reduce inflammation, fever, and pain by blocking the enzymes
Analysis of Aspirin Tablets Aim --- To discover the percentage of acetylsalicylic acid in a sample of aspirin tablets. ----------------------------------------------------------------- In order to do this, the amount of moles that react with the sodium hydroxide must be known. This is achieved by using the method of back titration. In this, the amount of moles in the sodium hydroxide solution after it has been reacted with the aspirin is found using
commercial aspirin tablet, using the principle of back titration. (II) Discussion Back titration rather than direct titration was used because there was no suitable indicator for acetylsalicyclic acid and sodium hydroxide solution. Therefore, excess amount of NaOH was used to react with acetylsalicyclic acid. The number of moles of unreacted NaOH was determined from titration with hydrochloric acid. Eventually the number of moles of acetylsalicyclic acid and its percentage in the commercial aspirin tablet
was not very pure. We calculated that we had about 14% Salicylic Acid in our purified sample. We claim that a safe dose of our aspirin to take is 7.06 milligrams or 84.72 milligrams in day. Introduction: Acetylsalicylic Acid or more commonly known as aspirin, is a nonsteroidal drug used as a moderate pain reliever, a fever reducer and for anti-inflammatory
Aspirin was prepared according to the protocol provided on Blackboard. The three sections to this experiment were 1. Synthesis of Aspirin, 2. Recrystallization of Aspirin, and 3. Characterization of Aspirin. In the first section, the Synthesis of Aspirin, salicylic acid was weight to be 3.029 grams using mass by difference since it was weighed on a 150 milliliter beaker. 9.23 milliliters of the acetic anhydride and 14 drops of 85 percent phosphoric acid were added to this beaker. A Bunsen burner
Aspirin (C9H804) Most people know Aspirin as a pill to take when they have a headache or some other ailment. There’s much more to Aspirin than most people know about. This report will explain the chemical properties of Aspirin as well as what the uses are, the history of the chemical, and the discovery of the molecule. Aspirin is also known as Acetylsalicylic acid. It is composed of nine Carbon atoms, eight Hydrogen atoms, and four Oxygen atoms. There are many chemical properties to it. The melting
hexanes, ethyl acetate, and 75% ethyl acetate and 25% hexane; the solution of 75% ethyl acetate and 25% hexane was determined to be the best solvent. This is due to the larger variance in RF values. The six standards that Motrin was tested against were Aspirin, ibuprofen, acetaminophen, naproxen sodium, caffeine and a caffeine and ibuprofen mixture. To determine which standard was present in the chosen drug, the retention factors, or RF, were calculated. A UV light was also used to see the distance each
If it is a substance like a sleeping pill, aspirin, or others within this category will decrease the heart rate. Each of these effects has a mechanism of action, to explain; adrenalin also has another name and that is epinephrine. The action that it takes is that it is an alpha and a beta-adrenergic
Analgesics "An aspirin a day keeps the doctor away." Although this saying can be true, it is not only aspirin that can cure the pains of life, but also several other types of analgesics. There are a wide variety of analgesics. More commonly known as painkillers. The narcotic analgesics act on the central nervous system and change the user's perception; they are more often used for severe pain and can make the user develop an addiction. The nonnarcotic analgesics, known as over the counter or OTC
Competency standards are constructed to describe all the fundamental qualities which are attained by an individual based on knowledge and experience, and together enable the individual to practise effectively as a professional. The National Competencies Framework provides a set of diverse guidelines for training pharmacists to develop into a qualified health professional who can ultimately promote the quality use of medicines in Australia. Competency Standard 4.2.2 revolves around the review of
thought to be triggered by aspirin use. The actual origin of the disease is unknown. Reye's Syndrome, occasionally called Reye-Jacobsen's Syndrome, is known to follow any viral infection. Two of the most common viral infections it precedes is influenza, “the flu”, and chicken pox. A now-familiar warning on bottles of aspirin, most notably Tylenol, is not to give Tylenol to a child who is recovering from the chicken pox, a fever, or any other viral infection. The link between aspirin and Reye's Syndrome
