Question

how would you separate dyes in black-black ink using
chromatography

Kirti Gogia · Accepted Answer

The black ink is basically a mixture of two dyes - blue and red
These two dyes can be easily separated with the help of
chromatography Chromatography is usually carried out with the help
of a special type of filter paper, called the Whatman's filter
paper
1) Take a thins strip of whatman's filter paper
2) Draw a line on it using a pencil, approximately 3 cm above
the lower edge
3) Put a small drop of ink either from a sketch pen or fountain
pen at the centre of the line Allow it to dry
4) Lower the filter paper into a glass jar containing water so
that the drop of ink on the paper is just above the water level
Carefully, cover the mouth of the jar with a lid and leave it
undisturbed
5) As the water rises up on the filter paper, the components of
black ink are separated
Remove the filter paper after some time Let it dry You will see
three different spots on the filter paper - one for the pure
solvent that is water, one for blue dye and one for red dye
