The purpose of this lab is to identify the composition of a mixture using Thin
Layer Chromatography (TLC)
TLC is one type of chromatography out of many. However the general concept of
chromatography stays the same: mixtures are separated b

Introduction
In this experiment, the progress of a reaction will be monitored using Thin
Layer Chromatography (TLC), and a solution would be separated by extraction using
a separatory funnel.
The method of extraction in organic chemistry is used to separa
