Discussion: The two dyes identified were disperse blue 3 and disperse red 9. Disperse red 9 separated first because it is less polar than disperse blue 3.

Disperse blue 3 is more polar because it has a hydroxide bond and has a larger dipole. The principle behind using column chromatography is that it separates compounds based on polarity. The alumina serves to allow
