Solutions Flashcards
1
Q
Molarity
A
mol of solute/ L of Solution
2
Q
Molality
A
mol of solute/ kg of solvent
3
Q
Boiling Point Elevation
A
Δ T= iKbm
When a solute is added to a solution, the boiling point increases
4
Q
Freezing Point Depression
A
Δ T= iKfm
When a solute is added to a solution, the freezing point decreases
5
Q
Vapor Pressure Lowering, Raoult’s Law
A
Pa = P(X) X= mole fraction
6
Q
Osmotic Pressure
A
The pressure required to keep a solution from diluting itself, once the solvent has been separated from the solution
λ= (nRT/V)*i= MRTi
^ Osmotic Pressure
7
