Question

1. Is the freezing point and melting point of pure lauric acid the same or different? Why?

2. How should you dispose of lauric acid/benzoic acid after the experiment is complete? Why?

please solve both questions.

Answer 1

1. the melting point and freezing point of a compound are the same. Because melting point and freezing point describe the same transition of matter, in this case from liquid to solid (freezing) or equivalently, from solid to liquid (melting).

2. Once the experiment is completed, the test tube with the probe should be placed in the hot water bath and allow the solids to melt. Once the solids have melted pull out the temperature probes and wipe them clean with a paper towel. The samples should be poured into a waste container provided or re-used by the next group.
