Experiment: The Role of Chemists in the Advancement of Medicinal Chemistry
Objective:
- To demonstrate the role of chemists in the development and synthesis of new drugs.
- To highlight the importance of medicinal chemistry in improving human health.
Materials:
- Aspirin tablets (2)
- Sodium bicarbonate solution (10 mL)
- Iodine solution (5 mL)
- Beakers (2)
- Stirring rod
- Test tubes (2)
- Dropper
Procedure:
- In one beaker, dissolve an aspirin tablet in 5 mL of water.
- In another beaker, dissolve an aspirin tablet in 10 mL of sodium bicarbonate solution.
- Add a few drops of iodine solution to each beaker.
- Observe the color change in each beaker.
- Transfer the contents of the beakers into two separate test tubes.
- Using a dropper, add a few drops of sodium thiosulfate solution to each test tube until the iodine color disappears.
- Compare the rate of reaction in each test tube.
Observations:
- The aspirin tablet dissolved in water turned a purple color when iodine solution was added.
- The aspirin tablet dissolved in sodium bicarbonate solution turned a brown color when iodine solution was added.
- The rate of reaction was faster in the sodium bicarbonate solution than in the water.
Discussion:
The experiment demonstrates the role of chemists in the development and synthesis of new drugs. The aspirin tablet dissolved in water turned a purple color when iodine solution was added, indicating the presence of salicylic acid. Salicylic acid is a precursor to aspirin, and it is converted into aspirin in the presence of sodium bicarbonate. The aspirin tablet dissolved in sodium bicarbonate solution turned a brown color when iodine solution was added, indicating the presence of aspirin. The rate of reaction was faster in the sodium bicarbonate solution than in the water, indicating that the sodium bicarbonate catalyzed the reaction.
This experiment highlights the importance of medicinal chemistry in improving human health. Aspirin is a widely used pain reliever and anti-inflammatory drug. The development of aspirin was a major breakthrough in the treatment of pain and inflammation. Chemists continue to play a vital role in the development of new drugs to treat a variety of diseases.
