Cut 8 5 cm square pieces of brown paper. Using a pencil number the square pieces of brown paper with numbers 1 8. Using a pipette put one drop of each unknown solution on the corresponding brown paper and allow it to sit for exactly 30 seconds. After 30 seconds remove the sample (wipe it off the paper) and observe the spot the sample left. Observe very carefully. Record your results as part of the following table. NOTE: Do water and oil first so you have a comparison for other samples. Water will be negative for lipids and oil will be positive. In the following table for unkown samples you will indicate whether each solution is positive or negative for lipids.
Complete the following table for the unknown samples using results of tests I IV.
