The aim is to identify six unknown over-the-counter drugs using different analytical techniques.
Utilized three analytical techniques: presumptive tests, thin layer chromatography, and nuclear magnetic resonance.
Performed color spot tests (Cobalt thiocyanate and Marquis) for initial identification.
Applied TLC for separating and narrowing down possible identities of the unknown drugs.
Employed NMR to determine the organic structures and confirm drug identities.
Successfully identified six OTC drugs including Aspirin, Aleve, and others.
Demonstrated effectiveness of multiple analytical techniques in forensic identification.
Highlighted student engagement and learning through hands-on laboratory experience.
