Chromatography

Aim: To separate the different pigments in inks or dyes using filter paper

Equipment:
markers
beaker
a strip of filter paper
scissors
pencil

Method:
1. Cut  a strip of filter paper that is long enough to reach the bottom of the beaker
2.put a line on the filter paper a finger away from the bottom of the paper.
3.fill your beaker so the ink dot doesn't get wet.
4.place a dot on the line. the dot needs to be concentrated
5.wait to see what happens.

Discussion:
The ink on the filter paper went down as the water went up. I learnt that water carries the ink down and the solvent that I was using dragged the ink down.
