How could you separate the pigments which make up a dye?

Separating Compounds: Chromatography

Separating Compounds: Chromatography 1. In an evaporating dish place 2 skittles of the same colour and 1 drop of water 2. Prepare you filter paper as shown 3. Put a layer of water in your beaker, about 2 cm 4. Carefully build up a concentrated dot of dye 5. Carefully place your filter paper in the water Do not let the water touch the dye directly!

Prepare a piece of filter paper to separate the dye in a pen… choose black and a secondary colour.
