Learning Objective
I can separate the different pigments in ink using chromatography.
- 1
Black ink is typically a mixture of different colored pigments, not a single color.
- 2
In paper chromatography, the paper strip acts as the stationary phase, while the solvent acts as the mobile phase.
- 3
Chromatography separates substances based on their different affinities for the stationary and moving phases, causing them to move at different speeds.
