Chromatography Lab-Experiment #3

Overview

Materials Needed:

2 Sheets White Copy Paper

600 mL Beaker

Number 2 Pencil

Food Coloring with the 4 basic colors (yellow, red, green and blue)

Rubbing Alcohol (Isopropyl Alcohol)

Source of Tap Water

**Note #1: Copy Paper Alternative

Since the Copy Paper contains materials such as but not limited to cellulose, clay, and titanium, coffee filters can be used to substitute. If you choose to use coffee filters in place of Copy Paper please omit Section 2 and do the following.

Take a Round Coffee filter and flatten it out on the table. You want to create a piece of the coffee filter wide enough to hold all the color options, and tall enough to suspend in the beaker. Measure 1 inch (2.54 cm) from each side shown in figure 3.1. Using only your No. 2 pencil draw a line that you will cut. Refer to #3 page 14 for further instructions.

Alternative 2.

**Note #2: Mixing Colors

When you are mixing the food coloring to make different colors please refer to the back of the food coloring box for instructions on how many drops of each color to add to create the desired colors.
