Before this experiment, ink was just the colour it was. Blue was blue, black was black, red was red and so on and so forth. However, after an experiment conducted using paper chromatography (again), black ink can be concluded that it is not fully black but more of a mixture of inks.
Now a more detailed explanation on how we should conduct paper chromatography:
1)At one end of the filter paper, mark a ink spot as shown
2)Place the filter paper in between 2 split corks
3)Fill the boiling tube with ethanol and water mixture to around 2cm
4)Lower the strip on filter paper into the boiling tube and make sure the ink spot is just above the liquid level
Though in many science worksheets that show paper chromatography, the points are always alligned very nicely into one straight line. As for mine, in went spiral.
However, what amazes me again, is how paper chromatography works, with the least amount of the item used, we are able to find out the substances in the item.
