Q
What does chromatography separate?
Describe the process.
A
Chromatography separates dyes from an ink.
- on filter paper, draw a baseline and put a drop of ink on the line
- place the filter paper in a solvent, water or ethanol (depending on ink)
- after putting a lid on the container (preventing evaporation), the solvent will seep up the paper carrying the dyes at different rates
- you will get a pattern of different dots called chromatogram.
