However, it can be considered to be glycine because of the difference lab in retention factor and slight difference in colour. Solvent distance, spot distance, rf, ury.30.7.29, gly.30.5.86. Conclusion The proposed hypothesis was correct. Calculate a ratio for each color by dividing the distance the color traveled by the distance the solvent traveled. Leaves appear green because chlorophyll is a very poor absorber of green wavelengths, therefore it reflects green light the best. It still remains unknown, but closer to glycine in identity. Analysing the colour of one of the mixture (the unknown mixture at spot 5) compared to the known amino acids especially the arginine, it was noted that they are more of the same purple colour. Black ink is a mixture of several different colors. The same idea will happen. This results in less light during the day for the plant to undergo photosynthesis. How many colors separated from the black ink?

Another color may have been present. Specifically, of the unit 6 lab report paper chromatography solvent is to dissolve the mixture needing to be separated. The results clearly show the relationship of the unknown unit 6 lab report paper chromatography mixtures to the known amino acids.

Methods, irom spotting of the known four amino acids and two unknown mixtures are then done using separate toothpicks which will help prevent contamination. Draw a solid 5mmwide band about 25 mm from the bottom of the paper. The carotene traveled the fastest because it displaced the furthest distance in a period of time. The laboratory procedures entail different steps that eventually lead to identification of the unknown mixtures.

Yellow 70 mm 111.63, pink 82 mm 111.74, red 101 mm 111.91, purple 110 mm 111.99, blue 111 mm 111.0, questions.As the solution travels up the paper, like soluble pigments will travel with the solvent until the bonds between the solvent and pigment become so weak that it must break the attraction and imprint itself a certain height up the paper.
