Examples
-
This freezing point depression is not colligative (although the depression of the melting point is) and is lost when the fluid is dialyzed through a molecular sieve with a cutoff of about 2500.

It is not yet known whether aquaporins play a role in accelerating the large cellular water losses that must accompany freezing for colligative cryoprotection to be effective.

The advantage of AFP's over colligative freezing point depression is in the much lower concentrations required and the ability to concentrate these molecules in the gut, where ice contamination is likely.

This occurs primarily by the mechanism of colligative cryoprotection, as in terrestrial animals.

There are some insect species found in the Canadian Rockies that have supercooling points of - 60°C, combining colligative freezing point depression with an absence of ice nucleation sites to avoid ice formation at any terrestrial temperature (although these species are also freeze tolerant, there is simply no chance for them to experience temperatures of - 60°C except in the laboratory).

When this happens, the AFP's will be incorporated into the crystal as defects, rather than excluded as colligative solutes.

The cryoprotectants used are colligative in action, glucose and glycerol are two of the most common cryoprotectants (a particular species confines itself to the use of a single cryoprotectant).

-
Such a multicomponent approach to freezing point depression allows a significant colligative action without bringing any one solute to the point of chemical toxicity.

-
The mechanism of cryoprotection appears to be simple colligative action, as in cryopreservation, with the additional benefit of stabilization of protein structure against low temperature denaturation.

How do I solve this "colligative properties" chemistry question?
