Description In our hands-on Purification of Caffeine lab project, students engage in learning various purification techniques while extracting and refining caffeine from readily available over-the-counter tablets. Key methods explored include crystallization, sublimation, and deposition. Traditional chemistry education often demonstrates sublimation using naphthalene, a compound found in mothball products used for clothing storage. However, heating naphthalene for sublimation in educational … [Read more...] about Discover the Chemistry of Caffeine Through Hands-On Lab Techniques
