Colligative Properties Flashcards
1
Q
Colligative Properties
A
don’t depend on the identity of solute, instead depends on the total number of dissolved particles
2
Q
Vapor Pressure Reduction
A
reduces area available for solvent particles to evaporate and escape
3
Q
Raoult’s Law
A
P=XaPa (P=vapor pressure of solution and Pa= vapor pressure of solvent)
4
Q
Boiling Point
A
temperature at which vapor pressure equals atmospheric pressure
5
Q
Solute addition on vapor pressure
A
adding solute increases BP and decreases vapor pressure (makes it harder to boil and harder to freeze)
6
Q
Boiling Point Elevation
A
Delta Tb=iKbm
7
Q
Freezing Point Depression
A
Delta Tf=iKfm
8
Q
Osmotic Pressure
A
pressure required to prevent osmosis
pi=iMRT (where M=molarity)
