Which one of the following methods is used to separate the colors in food dyes?

Answer 1

To separate food coloring and water you put the two into a glass. Then you put a pice of celary into it. The food coloring will run up the roots of the celary. If left long enough the celary will turn the colour of the food colouring leaving water behind.

Answer 2

Chromatography is used to separate pigments. The word comes from the Greek: 'chroma' meaning colour and 'graphein' meaning to write.

To analyse a mixture, thin layer chromatography (TLC) is commonly used (often simple paper chromatography is carried out in schools). TLCs are performed on a sheet of glass, plastic, or aluminum foil, which is coated with a thin layer of adsorbent material, usually silica gel, aluminum oxide, or cellulose. This layer of adsorbent is known as the stationary phase.

After the sample has been applied to the plate (or paper), a solvent or solvent mixture (known as the mobile phase) is drawn up the plate via capillary action. Because different pigments ascend the TLC plate at different rates, separation is achieved.

Preparative chromatography can also be carried out to isolate one or more components of the mixture.
