Purifying Chemicals by Distillation
Procedure and Observations
A simple distillation apparatus was set using the apparatus in the locker assigned.
50mL of 50:50 mixture of 2-propanol and 1-butanol were added to the distill

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
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
