MATERIALS Safety goggles pencil, ruler and scissors methanol chromatography paper plastic wash bottle ethanol 4 50ml graduated cylinder food coloring mixture 2-propanol 4 cork stoppers distilled water acetic acid 4 wire paper clips ethyl acetate 1 capillary tube cyclohexane PROCEDURE 1. Using a ruler; draw a straight pencil line across the chromatography paper, about 1.5cm from the bottom. 2. Use the capillary tube to put one small drop of dye on the pencil line. Let it dry. Repeat step 1-2 for other 3 trials with different developing solvents. 3. Fill each of four 50ml graduated cylinders with four different solvents you choose to about 5 ml. Use a cork stopper to suspend each filter paper strip in a graduated cylinder, as shown in Figure 4.1. The end of the filter paper should be below the solvent level; the dye spot should be above the solvent level. Permit the solvent in each graduated cylinder to rise up the filter paper until it is about 2cm from the top of 4. partices, (atoms or Tonst Remove the strips from the graduated cylinders. Using a pencil, mark on each strip the distance the solvent uncan u the paper. 5. has traveled from the point of origin. Record these distances as D; in a data table. 6. Measure on each paper strip the distance each dye spot has traveled. Record these distances as Dş. If the original dye spot has separated into several spots, measure and record the D, for each spot. Calculate the Rf value for each components in the dye for all trails. 7. Dispose and recycle materials according to teacher's instruction.
