Procedure
1. Cut a 3x3 aluminum foil. On the aluminum square, use a
marker to label the 3 locations of substances (A, B, and C),
evenly-spaced in a ring.
2. Place a few crystals of sodium chloride, crushed aspirin, and
sucrose, and acetaminophen (or ibuprofen) next to the marker
locations on the aluminum square. Try to make the amount of
each substance about the same. Do not allow the samples of
crystals to touch.
3. Write a brief description of each of the three substances in
Table 1.
4. Place the aluminum square on a frying pan and place them on
top of the stove. Try to get the foil as flat as possible.
5. Turn on to medium heat.
6. For this experiment, it is not necessary to have exact values
for the melting point. The foil will continue to get hotter as it
is heated, so the order of melting will give relative melting
points. Note the substance that melts first. Record the order of
melting for the other substances. Record as well the time it
takes for the first signs of melting for each substance.
5. After 5 minutes, record in Table 1 for each substance that did
not melt by encircling it. Turn off the stove. Allow the
aluminum square to cool while you complete the remainder of
the experiment.
6. Put a few crystals of each of the solids in your ice tray.
7. Using a dropper, add 10 drops of water to each well in the first
set of 3 substances. DO NOT STIR. Record the solubility of
each substance in Table 1 by writing "S" for soluble, or “NS"
for not soluble.
8. Add 10 drops of ethanol from the ethanol vial to each well in
the second set of 3 substances. DO NOT STIR. Record the
solubility of each substance in Table 1 by writing “S" for
soluble, or “NS" for not soluble.
