Observing Physical and Chemical Changes A. In this section, a sample will be examined to see how it interacts with fire, in other words, whether this sample is flammable or not. Being flammable is a chemical property. You will also be checking to see how this sample responds to heat. Based on the observations, decide whether a physical and/or a chemical change has taken place. Obtain one piece of aluminum foil and place it on a wire gauze on the ring clamp. Carry out steps 1-5 in the order. Record your observations in the table. Allow the foil to cool before beginning the next procedure. Recycle the aluminum. 1. a) Place two drops of water on the foil. Bring a lit wood splint near (but not touching) the surface of the water sample to see if it catches fire or not. b) Place two drops of water on the foil. Heat the liquid sample gently with the Bunsen burner from below. Continue heating for - 30 seconds after you start observing changes. 2. a) Place two drops of isopropyl alcohol on the foil. Bring a lit splint near (but not touching) the surface of the alcohol sample to see if it catches fire or not. b) Place two drops of isopropyl alcohol on the foil. Heat the liquid sample gently with the burner from below. Continue heating for - 30 seconds after you start observing changes. 3. This part needs to be done in the fume hood because of the harmful fume being generated. a) Place a pea-sized scoop of sugar on the foil. Bring a lit splint near (but not touching) the surface of the solid to see if it catches fire or not. b) Place a pea-sized scoop of sugar on the foil. Heat the solid sample gently with the burner from below. Continue heating for - 30 seconds after you start observing changes. 4. This part needs to be done in the fume hood because of the harmful fume being generated. a) Place a pea-sized scoop of ammonium chloride on a piece of aluminum foil. Bring a lit splint near (but not touching) the surface of the sample to see if it catches fire or not. b) Place a pea-sized scoop of ammonium chloride on the foil. Heat the solid sample gently with the Bunsen burner from below. Continue heating for - 2 minutes after you start observing changes. 5. Observe/record the color of a piece copper wire. Heat the wire in the Bunsen burner flame for a couple of minutes. Observe/record the color of the copper wire after it is taken out of the flame.
