Study Set Content:
the amount of substance diffusing
in time, across a plane of area is directly proportional to the
change of concentration with distance traveled.
Fick’s first law,
The osmotic pressure, π, of a dilute colloidal solution is
described by the van’t Hoff equation:
π = cRT
The osmotic pressure, π, of a dilute colloidal solution is
described by the van’t Hoff equation: π = cRT
Osmotic Pressure
One that is capable of accepting protons from the solute:
acetone, ether, liquid, ammonia
Protophilic (basic solvent)
Proton donating compound and is represented by acids:
formic acid, acetic acid, sulfuric acid, liquid acid, liquid HF.
Protogenic
Act both proton acceptors and proton donors: water,
alcohol, acetic acid
Amphiprotic
Neither accept nor donate protons useful for studying the
reactions of acids and base in the absence of solvent
effects.
Aprotic
Those made up of strong dipolar molecules having
hydrogen bonding (water or hydrogen peroxide)
Polar solvents
Those also made up of strong dipolar molecules but that do
not form hydrogen bonds (acetone or pentyl alcohol)
Semi-polar solvents
Those made up of molecules having a small or no dipolar
character (benzene, vegetable oil, or mineral oil)
Nonpolar solvents
The velocity, v, of sedimentation of spherical particles
having a density p in a medium of density po and a viscosity
no is given by
Stoke’s law
This can be accomplished with the use of centrifuge
Sedimentation
Stoke's Law
V1
terminal settling velocity of the solid particle
g
gravitational accelaration
Di
Density of settling particle
Dw
density of water
d
diameter of particle
u
dynamic viscosity
An expression of the resistance to flow of a system under
an applied stress.
