Paper Chromatography (Practical)

Until now, I still can't resist the thought of dropping all my unwanted worksheets into water, even though I know that's not how it is supposed to be done.

The practical was a very simple and straightforward practical, and it only took a couple of minutes at most, but it is one of the most memorable experiments I had in the chemistry module.

I always like colour combinations, but to think that a blue pen would contain so much red and yellow colours still sets me thinking.

Component	Distance moved by spot/cm	Distance moved by solvent/cm	Rf
Yellow	5.0	10	0.50
Red	1.0	10	0.10
Purple	0.5	10	0.05
Blue	1.0	10	1.00

After doing more research, I found out that there were different types of paper chromatography, including:

1) Ascending Paper Chromatography

2) Descending Paper Chromatography

3) Ascending-Descending Paper Chromatography

4) Horizontal Paper Chromatography

5) Two-Dimensional Paper Chromatography

Also, I found out that there is also a different type of paper chromatography, known as Thin-Layer Chromatography.
