As the solvent traveled up the paper, which color of ink appeared first?

The color orange first appeared as the solvent traveled up the paper. List the colors in order, from top to bottom, which separated from the black ink. The colors separated in this order, from top to bottom: From your results, what can you conclude is true about black ink? Black ink is a mixture of several different colors. Why did the inks separate? The inks separated because the black ink was a mixture of different pigments with different molecular characteristics.

These differences allow for different rates of absorption by the filter paper. Why did some inks move a greater distance? The ink least readily absorbed by the paper would then travel the farthest from the starting mark. You can conclude from this information that the different pigments were absorbed at different rates. Error Analysis Possible errors could include inaccurate measurements of the distances traveled by the inks and mistakes when calculating the ratio traveled by the water and colors.

If a longer test tube was used, a longer strip of filter paper could have been used. This may have changed the ratios. Another color may have been present, but not detected because of the filter paper length. Conclusion The proposed hypothesis was correct. The paper chromatography did show that black ink could be separated into various colors. The black ink gets its color from a mixture of various colored inks blended together.
