Abstract: Using paper chromatography the separation of the colors in green dye was done. With the use of chromatography, it was proven that green colored dye is a mixture of blue and yellow dye.

Procedure: Refer to Experiment 23 in Utecht, R.; Downey, T; Miller, M; Hirko, R. Chem 112L-General Chemistry I Laboratory, 3 rd ed., Cache House, Inc: Eden Prairie, MN, 2009. Observations: The green dye had moved up the paper and had two spots, a yellow and a blue one. The yellow spot from the green dye was measured at 2.2 cm. The blue spot from the green dye was measured 3.1 cm. (This is probably an error and the spot may have moved past the solvent front while the paper was drying before being measured.) The yellow dye measured 2.4 cm. The blue dye
