Background Info. And Research
 Paper Chromatography is qualitative

method used to detect substances dissolved in a solution. This is created from substances you wish to test for. You blot small amounts of each ion on developing paper and placing them in a developing solvent and the product of the following will be your Chromatography.

Purpose
 This shows how you can separate

different organic compounds from a mixture using variations in solubility, size of the molecules and retention by the paper being used to separate the compounds.

Materials
 Candy that has color coating
 Rubbing Alcohol
 Coffee filters
 Plastic cups
 Pencil
 Ruler
 Tape
 Foil
 Table Salt
 Tooth picks
 Measuring spoones
 2 liter bottle

Procedure
1. I first cut the two circular coffee filters into 3in by 9in

rectangles.
I then drew a straight line 1in above the bottom of the filter. Next I marked four colored dots across the line 1/2in apart, and labeled them.
To make the salt solution I mixed 1/8Th inch of salt in with
3 cups of water.
Taking one of my glasses, I filled it with about a 1/4Th inch of my solution.
Taping my coffee filter around my pencil, I laid it in the solution where it touched the bottom but not the colors.
I then repeated these steps with alcohol instead of the salt solution.
