Solutions & Colligative Properties Flashcards
1
Q
Freezing Point Depression
A
dT = K *m * i
K - freezing point depression
m - molality of solution
i - van’t Hoff coeficient
2
Q
Boiling Pont Elevation
A
dT = K *m *i
3
Q
Vant Hoff coefficient
A
i=1+α(z−1)
z - ions
α - fraction dissociated
4
Q
Molality (m)
A
kg of solvent, uaffected by T nor P
5
Q
Molarity (M)
A
liters of solution, can change with T
6
Q
Osmotic Pressure
A
Π=iMR*T.
7
Q
What Polar solvents dissolve?
A
Polar solvents[like water] dissolve ionic and polar substances
8
Q
What non -Polar solvents dissolve?
A
non-polar solents dissolves non-polar molecules
9
Q
molality formula
A
molality = moles of solute/mass of the solvent[kg]
