Explanation:
Chromatography (literally translated means "color writing") is one way in which mixtures can be separated. The isopropyl alcohol will move up the chalk by surface tension, similar to how water is absorbed into a napkin. As the alcohol moves up the chalk, it picks up the ink pigment as it travels.
