Separating Food Dyes Using Chromatography

Students use paper and column chromatography to separate colored food dyes in a common grape-flavored drink mix.

This lab is an introduction to molecule-molecule interactions. The chemical composition of food dyes will be correlated to their polarity and thus, to their ability to bind to solid matrices and liquid media used in chromatography.
