individually. This is 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

Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and
