Twelve - Colligative
Osmotic Pressure This
animation shows the separation of a solvent
and a solution by a semipermeable membrane,
osmosis, and osmotic pressure.
Vapor Pressure Aqueous Solution This
animation shows the transfer of solvent
from a solution of low concentration
to a solution of high concentration through
the vapor phase.
Point Elevation Lab Document
is the document for the boiling point
elevation of ethylene glycol lab.
Lauric Acid FP Depression Lab Document
is the document for the lauric acid freezing
point depression lab.
Introduction Chapter 12
This video is the
introduction to Chapter 12 of the web course. VIDEO optional
video shows the effect of adding antifreeze
on the freezing point of water. VIDEO
Boiling Point Reduced Pressure This
video shows the decrease in the boiling
point of water by decreasing the applied
Vapor Pressure and Concentration This
video shows the transfer of water from
a solution of low concentration to a
solution of high concentration based
on the difference in vapor pressure.
Osmotic Pressure Dialysis Tubing This
video shows the flow of water through
dialysis tubing into a sample of molasses.
Freezing Point Depression NaCl This
video shows the decrease in the freezing
point of water by adding salt.
Volatility of Acetone and Water This
video shows the relationship of volatility
to intermolecular forces.
Boiling Point Elevation Lab This
video shows the measuring of boiling
point of different solutions of ethylene
glycol and the determination of relationship
of the boiling point elevation to various
concentration units. The boiling point
elevation of water is determined. (
Lauric Acid FP Depression Lab This
video shows the collection of data for
the freezing point depression of lauric
acid and the determination of the molar
mass and molecular formula of an unknown
compound. ( )
