Station #1
Mg (s) + 2 HCl (aq)  MgCl2 (aq) + H2(g)
Materials:
1 dropper
2.0 mL 1.0 M HCl
1 piece of Mg ribbon
1 test tube rack
1 10 mL graduated cylinder
1 small test tube
1 forceps
1 bottle of distilled water
HAZARDS: Hydrochloric acid (HCl) is corrosive and can cause burns.
Procedure:
1. Use the dropper and graduated cylinder to measure out 2.0 mL of the HCl.
2. Pour the HCl into the small test tube.
3. Use the forceps to place the piece of Mg ribbon into the test tube.
4. Observe the change.
5. Pour the contents of the test tube into the WASTE beaker.
6. Rinse the test tube thoroughly with the distilled water, and pour the rinse
water into the WASTE beaker.
Station #2
H2O ()  H2O (g)
Materials:
1 dropper
1 bottle of distilled water
1 Bunsen burner
1 test tube rack
1 test tube holder
1 10 mL graduated cylinder
1 small test tube
1 sparker
1 heat resistant pad
1 30 mL beaker
HAZARDS: Use caution with gas burners. Hot glass looks like cold glass!
Procedure:
1. Use the dropper and graduated cylinder to measure out 2.0 mL of water.
NOTE: Take water from the BEAKER! Never put a dropper into a
distilled water bottle!
2. Pour the water into the small test tube.
3. Light the Bunsen burner with the sparker.
4. Adjust the burner until it produces a low flame (no inner cone).
5. Use the test tube holder to hold the bottom of the test tube over the flame.
6. Observe the change.
7. Pour the contents of the test tube down the drain.
Station #3
4 Fe (s) + 3 O2 (g)  2 Fe2O3 (s)
Cu (s)  Cu (s)
H2O (s)  H2O ()
Materials:
1 iron nail
1 piece of copper wire
1 250 mL beaker
1 ice cube
Procedure:
1. Observe the nail/change in the beaker.
2. Bend and twist the copper wire provided.
3. Observe the change.
4. Place a piece of ice in the palm of your hand.
5. Observe the change.
6. Place any leftover ice in the sink.
Station #4
2 Mg (s) + O2 (g)  2 MgO (s)
Materials:
1 piece of Mg ribbon
1 sparker
1 tongs
1 Bunsen burner
1 heat resistant pad
1 watchglass
HAZARDS: DO NOT LOOK DIRECTLY at burning magnesium, as intense
light can damage your eyes. Be cautious when working with gas burners.
Procedure:
1. Light Bunsen burner with sparker
2. Adjust the burner until it produces a low flame (no inner cone).
3. Hold a piece of magnesium with the tongs.
4. Place the tip of the magnesium in the burner flame.
5. Once ignited, hold the magnesium over a watch glass.
6. Observe the change.
7. Place the product in the WASTE beaker.
Station #5
NaCl (s)  NaCl (aq)
Materials:
1 dropper
1 bottle of distilled water
1 spatula (microscoop)
1 test tube rack
1 10 mL graduated cylinder
1 small test tube
1 g NaCl (sodium chloride, salt)
1 30 mL beaker
Procedure:
1. Use a dropper and graduated cylinder to measure out 2.0 mL of distilled
water.
NOTE: Take water from the BEAKER! Never put a dropper into a
distilled water bottle!
2. Pour the distilled water into the test tube.
3. Add a small spatula tip of sodium chloride (NaCl) to the test tube.
4. Swirl the test tube.
5. Observe the change.
6. Pour the contents of the test tube into the WASTE beaker.
7. Rinse the test tube with distilled water.
8. Pour the rinse water into the WASTE beaker.
Station #6
C3H7OH ()  C3H7OH (aq)
Materials:
2 droppers
2 10 mL graduated cylinders
1.5 mL isopropyl alcohol 1 bottle of distilled water
1 small test tube
1 test tube rack
Procedure:
1. Use a dropper and graduated cylinder to measure out 1.5 mL of distilled
water.
NOTE: Take water from the BEAKER! Never put a dropper into a
distilled water bottle!
2. Pour the water into the test tube.
3. Use a SECOND dropper and SECOND graduated cylinder to measure out
1.5 mL of isopropyl alcohol.
4. Pour the isopropyl alcohol into the same small test tube.
5. Swirl the test tube gently.
6. Observe the change.
7. Place the product in the WASTE beaker.
8. Rinse the test tube thoroughly with distilled water.
9. Pour the rinse water into the WASTE beaker as well.
