accomplished in this lab by the technique called thin layer chromatography (TLC). TLC involves a stationary phase‚ which the TLC plates as well as a mobile phase‚ which could be one of two solvents used: ethanol-acetone for TLC. Dyes in a sample separate consequently because of their unique polarities. As a result‚ nonpolar substances travel further than polar substances in this process. The separation of a mixture into its components by TLC transpires because the distinctive components of a mixture interact
