How to fill out lab 4 chromatography of

To fill out lab 4 chromatography of, follow these steps:

1. Start by gathering all the necessary materials for the experiment. This may include chromatography paper, a ruler, a pencil, a set of colored markers, a solvent (such as water or alcohol), and a beaker or glass jar.
2. Prepare the chromatography paper by drawing a horizontal line near the bottom using a pencil. This will serve as the baseline for your experiment.
3. Take a colored marker and draw a dot of ink on the baseline. Make sure the dot is small and concentrated, as this will be the sample to be separated during the chromatography process.
4. Carefully place the chromatography paper vertically in a beaker or glass jar, making sure that the dot is above the solvent level. The solvent should be about 1-2 cm deep.
5. Allow the chromatography paper to remain in the beaker, allowing the solvent to rise through the paper via capillary action. As the solvent moves up the paper, it will carry the different pigments of the colored marker with it, separating them based on their solubility.
6. Let the experiment run until the solvent front is about 1 cm away from the top edge of the paper. This may take some time, so be patient and observe the progress.
7. Once the solvent front has reached the desired height, carefully remove the chromatography paper from the beaker and let it dry completely.
8. Analyze the chromatography paper by observing the separated pigments. Measure the distance traveled by each pigment from the baseline to its leading edge. Record these distances and calculate the Rf value for each pigment using the formula Rf = distance traveled by pigment / distance traveled by solvent.
