Purpose (Hypothesis): To understand the process of chromatography, and see which color will have the greatest rate of seperation.
Materials:
Nine drops of blue dye; Fifteen drops of green dye, Twenty seven drops of yellow, Seventy drops of re-orange, 250 ml beaker, Absorbent, Water, Pipette
Procedures:
Gather Materials Fill Beaker W with approximately 50 milliliters of water Fill Beaker A with approximately 50 milliliters of alcohol Cut two pieces of absorbent paper with an approximate length of 15 centimeters each Using the pipette, squeeze one drop of the mixed dyes onto both absorbent papers high enough so that when they are placed in the beakers, the dyes will not touch the fluids Allow chromatography to take place over an extended period of time and record the results
Data:
Dyes in WaterRate
Blue.0404 mm/seconds
Green.0346 mm/seconds
Yellow.0334 mm/seconds
Dyes in AlcoholRate
Blue.0129 mm/seconds
Green.0102 mm/seconds
Yellow.0099 mm/seconds
Conclusion:
Chromatography, which is employed to split-up organic compounds from mixtures on the basis of their solubility in a solvent, is demonstrated in this lab. Chromatography takes place when the absorbent paper is placed in the two substances. After an extended period of time, the organic compounds in the mixtures break up at different rates, depending on their solubility in the water or alcohol. Blue had the greatest rate of separation in both substances, followed by green, and yellow. The mixture in the water moved up the paper about 3 times as fast as the same mixture in alcohol.

The Essay on Chromatography of M&M and Ink Dyes
Separations: Chromatography of M&M and Ink Dyes Almost all substances we come into contact with on a daily basis are impure; that is, they are mixtures. Similarly, compounds synthesized in the chemical laboratory are rarely produced pure. As a result, a major focus of research in chemistry is designing methods of separating and identifying components of mixtures. Many separation methods rely ...
