Do your background research so that you are knowledgeable about the terms, concepts, and questions listed in the Background tab.

Choose three colors of candies you want to test. Cut each filter paper in half length-wise to make approximately 2 centimeters cm wide by 7. You will need at least 30 chromatography strips. Use a pencil to lightly label which candy color or food coloring will be spotted on each paper strip.

Label 5 chromatography strips for each candy color and 5 strips for each Candy chromatography lab report coloring red, green, and blue.

Draw a pencil line 1 cm from the edge of each strip of paper, as shown in Figure 2 below. This will be the origin line. You will spot the candy color for each strip right on this line, as shown in Figure 2. Each chromatography strip will have an origin line. The dye to be tested will be spotted in the middle of the origin line.

Next you need to extract some dye from each candy you wish to test. Fill the mL beaker with some water. Use the pipet to put a single drop of water in the clean plate or plastic lid as shown in Figure 3 below.

Set one candy in the drop of water. If you use too much water, the dye will not be concentrated enough to see on the chromatography strip. How to use the pipet: Squeeze the pipet at its widest point. While continuing to squeeze, insert the narrow end into the beaker of water.

Release the wide end and the pipet will fill with water. Put the narrow end of the pipet directly over the petri dish. Gently squeeze the wide end of the pipet to release one drop of water. Leave the candy in the drop of water for three minutes to allow the dye to dissolve.

Remove the candy, then dip a pipet tip, or clean wooden splint tip, into the now-colored drop of water. Spot the candy dye solution onto the chromatography strip by touching the pipet tip, or a wooden splint, to the strip, right in the center of the origin line as shown in Figure 4 below.

Allow the spot on the strip to dry completely this should take approximately 1 minute. Repeat steps 6e to 6f three more times. You want to make sure to have enough dye on the chromatography strip so that you can see the dye components when they separate out on the paper.

Repeat steps 6b to 6g with four more strips and four new candies that are the same type and color e. To extract the candy dye, leave a piece of candy in a single drop of water for three minutes. When you remove the candy, a puddle of dye will be left behind.

Spot the extracted candy dye onto the paper chromatography strips using the tip of a wooden splint or a pipet.

Repeat step 6 for the other two colors of candy you want to test. In the end you should have 15 spotted chromatography strips— 5 for each colored candy type. You also need to prepare chromatography strips with food coloring dyes. These will be your known compounds, with which you will compare the "unknown" candy dyes.

For each food coloring color put a drop of coloring in the bottom of the petri dish. Dip a clean wooden splint tip or a pipet into the drop of food coloring. Spot the food coloring onto a chromatography strip by touching the wooden splint, or pipet, to the strip, right in the center of the origin line.

Repeat steps 8c to 8d until you have 15 chromatography strips spotted with food dye— 5 red, 5 blue, and 5 green. Also repeat step 8b if needed. Shake or stir until the salt is completely dissolved. Pour a small amount of the salt solution into the mL beaker.

Clip two of the prepared chromatography strips to a wooden splint.Transcript of Mixtures and Solutions: Lab Report. Data and Observations List your original predictions about the expected pigment components of each candy color.

Lab Report- Choice 1: Candy Chromatography Prediction I thought that the colors of the candy would fade off. Chromatography lab Purpose: To separate food colorings into their component dyes using paper chromatography. Materials: Chromatography paper, Food coloring, Ruler, Pencil, Solvent solution, Test tubes, Test tube rack.

Transcript of Chemistry - Candy Chromatography Paper chromatography is an analytical method technique for separating and identifying mixtures that are or can be colored, especially pigments. Candy Chromatography Separation of plant pigments is the most common use of paper chromatography in .

Using a solid support (like paper) to separate different kinds of molecules is called chromatography. Scientists use this method all the time in different experiments.

YOU are a chromatographer by performing the Candy Chromatography experiment.
