1
Q
Boiling point of water
A
- 100 C
- 212 F
2
Q
Boiling point of water with a solute
A
△Tb = imKb
3
Q
△Tb
A
- Change in the boiling point
- Add/subtract to original boiling point
4
Q
i
A
The number of particles the solute creates
5
Q
m
A
- molality
- the regents replaces this with molarity
6
Q
Molality vs Molarity
A
- m
- moles of solute / mass of solvent (kg)
vs. - M
- moles of solute / volume of solution (L)
7
Q
Kb
A
- boiling point of constant based off of solvent
8
Q
Kb of water
A
0.51 C kg/mol
9
Q
What does the solute do to the boiling point and freezing point?
A
- raises boiling point
- lowers freezing point
10
Q

Q
△Tf
A
Change in freezing point
13
Q
