Answer:
Solubility of the ink in the solvent
Component substances in the ink
Explanation:
Movement along the chromatography paper/fabric is determined by the solubility of the ink in the solvent and the component of the ink itself.
Chromatography is a separation technique used to separate complex mixtures.
The solution containing the mixture to be separated is spotted on a line near the end of the paper and then the paper is placed in a tank.
The solvent moves up the paper and it separates the mixtures in the spot into a number of different spots.
We can see that the solubility of the ink and component of the ink determines how they will be separated.
