1. Aphenomenon called supercooling is frequently encountered in thisexperiment. In supercooling, a solution momentarily drops below itsfreezing point, and then warms up again, before solidificationbegins. What allows supercooling to occur?

2.The molal freezing point constant, Kf , is a property of thesolvent, not the solute. The extent of freezing point depression onthe other hand is a property of the solute. Explain why Kf is aproperty of the solvent and the extent of freezing point depressiondepends only on the amount of solute.

3. Aphenomenon that happens sometimes during freezing point depressionexperiments is that the solute is affected in some manner by thesolvent. One common occurrence is for a solute to dimerize, thatis, two solute molecules combine to produce a single doublemolecule (a dimer). What effect would there be on a molar massdetermination if the solute were to dimerize?
