Unformatted text preview: and placed under a heating lamp to dry.Measured the distance the solvents moved and recorded it. Observed color of each cation, known and unknown and recorded it. Then the chromatography paper was stained and the colors were observed and recorded. The distance each cation and mixture moved was measured and recorded it. Calculated each Rf by dividing (The distance the solvent moved/ the distance the cation moved).Once all calculations and observations were completed each known cation was compared to the unknown mixture to figure out the corresponding cation. Returned all instruments and materials used, properly in their place. Data attatched Conclusion The two unknown mixtures that were selected to test corresponded to several cations. Unknown III was a mixture of fe + and unknown I was a mixture of Cu 2+ and Ag+...
