Answer 1

The drop of palm oil on the filter paper will stay as an oily, greasy spot without evaporating. The drop of petroleum spirit will evaporate quickly, leaving no visible residue. The drop of water will also evaporate, leaving a small amount of residue that may look white or clear. The drop of bromine water will react with the palm oil, turning from orange or brown to a colorless solution.
