candy chromatography
Background Information and Research Give a simple explanation, in your own words, of what paper chromatography is and what it is used for. Paper chromatography is to separate mixtures into their own. Give at least three real-world uses for paper chromatography used in the fields of chemistry and biology. This can be used to test for contaminants in rainwater, analysis of narcotics and detection of substances in urine. Be sure to include references for any research conducted for this section.

Purpose In one or two complete sentences, state the purpose of this laboratory investigation.
Materials Candy( skittles) colors: red, blue, pink, and green rubbing alcohol 2 coffee filters 2 glass cups pencil ruler foil water table salt cotton swabs measuring cup pitcher
Procedure Cut coffee filters in to rectangles 3cm by 9cm put 4 water drops on a piece of foil and put each piece of candy in the water . Drew a line 1cm from the edge of the paper put 4 dots on the line for each color dipped a cotton swab in each color and added to the coffee filter three times each mixed 1/8 teaspoons of salt and 3 cups of water in to a pitcher and shaked it until it was dissolved poured the salt water in to a glass cup so that the liquid level was ¼ inch put the coffee filter in to the salt water the dyes started to separate repeat steps 2-9 but with alcohol and not salt water
Data and Observations List your original predictions about the expected pigment components of each candy color. I thought that no color would move. Create an organized and labeled data table that lists the color and distance traveled of each pigment separated from each original candy color or ink type. Remember to have two separate sections or tables for the two solutions (salt water and alcohol) used other attachment. Also include any other observations that you made during the course of the investigation.
Discussion and Conclusion: A comparison of how each solution (salt water and alcohol) separated the pigments from each color of candy or ink type. Which solution worked better at separating each of the pigments (it may be different for different candy colors or inks), and why do you think that is? The saltwater solution worked better because there was more movement then the alcohol solution. If you had allowed less time for the lab (stopping the separation process when the solution was halfway up the paper), how do you think that would have affected your results? Yes I think it would nat have separated as much as it should. What pigment colors traveled farther up the paper? What pigment traveled the least? Was it the same or different when those pigments appeared in other candy colors or inks? Was it the same or different when separated by alcohol instead of salt water? Green traveled farther up the paper. Pink traveled the least. It was different when separated by alcohol because blue traveled farther and green traveled least
