Concentration
M = n / Vsolution, L
m = n / masssolvent, kg
Molarity uses solution volume. Molality uses solvent mass.Freezing point
ΔTf = iKfm
Tf = Tf° − ΔTf
ΔTf is a positive decrease. Use the given ideal van’t Hoff factor.Solubility
AaBb(s) ⇌ aA + bB
Ksp ≈ ([A]/c°)a([B]/c°)b
At saturation; c° = 1 mol/L. Omit the pure solid.Titration
n = MV, with V in L
nanalyte/νanalyte = ntitrant/νtitrant
ν is a coefficient in the balanced reaction. Use the mole ratio at equivalence.Assumptions for this problem
