Describe an experiment you could do to test the strength of intermolecular forces using melting point. Be detailed about how you would set the experiment up and what you would measure.

Answer 1

Experiment Setup:

1. Gather two samples of the same type of compound, one of which has been purified and the other of which has not been purified.

2. Place each sample in a separate beaker and measure the mass of each sample.

3. Place each beaker in a water bath and heat the water bath to a temperature of 100°C.

4. Measure the temperature of the water bath every 5 minutes until the sample in the purified beaker has completely melted.

5. Record the temperature at which the sample in the purified beaker has melted.

6. Repeat steps 3-5 for the sample in the non-purified beaker.

7. Calculate the difference between the melting points of the two samples.

Measurements:

1. The mass of each sample.

2. The temperature of the water bath at which each sample melted.

3. The difference between the melting points of the two samples.
