POINT
I. Objectives:
Correlate intermolecular forces of attraction and physical
properties (solubility, rates of evaporation and melting point) of some
samples.
II. Materials:
table salt, and mothballs
III. Procedure
Part A : Predict and Explain which substance melt faster.
Part B:
1. Place a small amount of sodium chloride into a test tube, just
enough to coat the bottom of the test tube.
2. Light the Bunsen burner and adjust the flame until a blue inner
core is achieved . An alcohol lamp may be used if a Bunsen
burner is not available.
3. Using a test tube , hold the test tube containing the salt at a
slight angle over the flame. Hold until the salt starts to melt.
Take note of the duration for the salt melting. If does not melt
within 15 seconds after heating proceed to Step 4. If it has
melted. proceed to step 5.
4. If the salt did not melt in step 3, lower the test tube until the
bottom of the test tube is within the blue inner core of the flame.
Note that the temperature of the flame increases from its outer
surface to the inner core. Hold in the same position for 15
seconds until the salt starts to melt. Record the time duration.
5. Place the test tube on a rack, and allow it cool.
6. Observe the contents of the test tube and record your
observations.
7. Repeat the procedure using sucrose and mothballs.
Guide Questions:
1. Predict which substance melt faster?
2. Is your prediction correct? If no, how does it differ to what you
had observed?
Note: Answer sheet will be provided by the teacher
