The objective (or purpose) of the experiment One of the leading over-the-counter drugs with the highest sales is aspirin. The drug is commonly referred as acetylsalicylic acid. As such, the medication was widely used in relieving pain, fevers, managing swellings. Currently, more than 19 million pounds of the drugs are retailed yearly in the USA. The drug is synthesized from salicylic acid. The acid is initially made from salicin. The above compound is majorly obtained from the bark a willow tree. The tree’s extracts have been exploited for centuries. As such, the use of its aqueous extracts to manage fever and aching was first testified in late 18 th century in Europe. In the middle 19 th century, salicylic acid was extracted a willow bark. The extracts were found to be a powerful analgesic and antipyretic products. The drug progressively hydrolyses when exposed to water or salicylic acids. Analgesic tablets usually comprise of aspirin, acetanilide, and sucrose. The mixture of these components is said to be used in managing migraine headaches. Acid-base extraction isolates these compounds since they have dissimilar acidities. The experiment sought to separate the different components of a VCU analgesic drug named Phensuprin. The product comprised of aspirin, acetanilide, and sucrose. Aspirin acts as an analgesic element. Acetanilide also serves as an alternative analgesic product. On the other hand, sucrose is used as fillers. In the experiment, these components were isolated based on the dissimilar solubility and reactivity of each respective constituent. After that, the quantity of each component in the mixture was determined. The melting point of each compound illustrated its purity. The key objectives of conducting the experiment are indicated below:  1. To understand the technique of acid-base extraction  2. To isolate aspirin from acetaminophen using the extraction technique  3. To understand the process of drying organic solvents and vacuum filtration  4. To investigate the purity of the aspirin and acetaminophen samples using HPLC exploration The structures (pictures), hazards, and physical properties of all reactants and products Aspirin is a white crystal-like and a feebly acidic substance. It exhibits a melting point of 136°C and a boiling point of 140°C. The compound has a molar mass of 180.157 g/mol. The product should be used under the direction of a physician because of its adverse effects. The drug causes gastrointestinal bleeding in patients allergic to aspirin 1 . Similarly, the drug can induce swelling of the skin tissues in some people. Indicated below is the chemical structure of aspirin: Fig 1: simple structural formula of Acetylsalicylic acid Acetanilide is derived from aniline. As such, the substance is white to gray solid in color. The component has a molar mass of 135.17 g/mol. It has a melting point of 237.7°F or 114.3°C. Signs of exposure to this material may comprise of contact dermatitis, cyanosis, and eczematous skin flare-ups 2 . Notably, the substance is an irritant. It releases poisonous vapors when heated to decomposition. Indicated below is the chemical structure of acetanilide: Fig 2: simple structural formula of acetanilide Dichloromethane is commonly known as methylene chloride. The product is an organic compound. The component has a molar mass of 84.93 g/m
