How to fill out chromatography lab worksheet

How to fill out chromatography lab worksheet

1. Start by gathering all the materials needed for the chromatography lab worksheet, including the chromatography paper, solvent, paperclip, filter paper, and the substances to be tested.
2. Cut a strip of chromatography paper and draw a pencil line near its bottom. Make sure the line is above the solvent level when the paper is suspended vertically in a test tube.
3. Using the capillary tube, place a small drop of the substance to be tested on the pencil line of the chromatography paper. Allow the drop to dry completely.
4. Add the solvent to the test tube, ensuring that the level is below the pencil line on the chromatography paper. The solvent should not touch the paperclip or filter paper.
5. Carefully suspend the chromatography paper vertically in the test tube, ensuring that the pencil line is above the solvent level. Use the paperclip to hold the paper in place.
6. Observe as the solvent travels up the chromatography paper and separates the different pigments present in the tested substance. Record your observations in the lab worksheet.
7. Once the solvent has reached the top of the chromatography paper, remove the paper from the test tube and mark the distance traveled by each pigment.
8. Use the filter paper to estimate the distance traveled by the solvent. This will help calculate the Rf value for each pigment.
9. Finally, clean up the materials used and organize the collected data in the chromatography lab worksheet for further analysis.
