Another Look at Freezing Temperature

Experiment #3 from Chemistry with Vernier

Education Level
High School


In the experiment, “Freezing and Melting of Water,” you saw that the temperature of pure water remained constant at its freezing temperature as it froze and melted. Using a computer-interfaced Temperature Probe, you will now observe what happens when a different pure substance, phenyl salicylate, freezes. Using a second Temperature Probe and sample, you will also see the effect on freezing temperature when a small amount of another substance, benzoic acid, is dissolved in the phenyl salicylate.


In this experiment, you will

  • Observe what happens when phenyl salicylate freezes.
  • See the effect on the freezing temperature when a small amount of benzoic acid is dissolved in the phenyl salicylate.
