You will use paper chromatography to test food colorings to see if the color results from a single dye or mixture of dyes. If you cannot get food coloring you can use colored felt pens or...

Paper or chalk chromatography is used to separate the components of dyes, inks, food coloring and other mixtures by their molecular size and their solubility in polar solvents-- such as...

recognize that mixtures can be separated by physical means. recognize that most inks are a mixture of colors. separate a mixture using paper chromatography. Motivation for Learning.

paper chromatography. food chemistry. for the different candy colors.

These then will be compared to colored food products to determine what colorings are used in coloring everyday foods. Demonstrate the procedure for completing a proper chromatography

The resulting dyes are then separated using paper chromatography. If commercial food colors are used as standards, the separated dyes can be identified.

Chromatography is a laboratory procedure that effectively separates individual components found in a mixture.

So we can do an ink chromatography or a food color chromatography to separate colored individual substances in the ink or food color. Now let's do an experiment.

Since there are only a small number of approved food dyes, you should be able to identify the ones used in the candies by comparison to the chromatography results for food coloring.

In this lab, you will explore two applications of chromatography - identification of an unknown ink sample and the separation of food colorings.

OBJECTIVE In this experiment, artificial food colors will be extracted from foods and paper chromatography will be used to separate and identify the synthetic food colors.

Try making a huge design on a whole sheet of paper towel. What happens if you test other water soluble things like Kool-aid, food coloring, or M&M's? All kinds of chromatography.
