Single class period (< 90 mins)
In this CLAW (Chemistry Laboratory Alternative Work) At-Home experiment, students will perform an experiment using household chemicals and materials. It was designed as a substitute for in-person laboratories, usually performed at the college level, during the COVID-19 pandemic. However, it may also be used as an experiment that students can carry out in the lab or for student projects.
Colligative properties of solutions depend on the quantity of solute dissolved in the solvent rather than the identity of the solute. The phenomenon of freezing point lowering will be examined quantitatively as an example of a colligative property in this at-home experiment.
