>From Textbook of CHEMISTRY: Boiling Point, Freezing Point, and Osmotic Pressure of Colloidal Solutions.
It is impossible to make more than a few general statements regarding boil- ing and freezing points and osmotic pressure. One colloid may be prepared by the application of heat, whereas another may be destroyed. In general, freezing destroys the colloidal state and causes coagulation of the dispersed phase. No valuable data pertaining to the molecular weight of colloids by boiling-point rise, freezing-point depression, or osmotic pressure determina- tions have been obtained because the effect of the colloid is too small to be measured. This is particularly true of the suspensoid type of sol such as the colloidal elements, hydroxides, and suifides. Higher concentrations of the dispersed phase are obtained with the emulsoid type of colloid, such as soaps, gelatin, glue, and starch. There is one marked difference between suspensoid and emulsoid sols. When heated to dryness the emulsoid sols can be re- peptized with water, but the suspensoid sols cannot. Emulsoid sols are called reversible sols; suspensoid sols are irreversible sols. 1. pure minerals form sols not solutions. 2. a hydrate is a compound formed by the chemical combination of water and some other substance. Sols are not combined but suspended. 3. pure mineral sols when dryed can not be turned back into sols by wetting. Judging from the above that below sounds suspect.
