Molarity
$M = \frac{moles of solute}{volume (L)}$
Molality
$m = \frac{moles of solute}{mass of solvent (kg)}$
Mole fraction
$x_{A} = \frac{n _{A}}{n _{A} + n _{B}}$
Raoult's law
$P = x_{so l v e n t} P^{\circ}$
Raoult's law (two volatile)
$P = x_{A} P_{A}^{\circ} + x_{B} P_{B}^{\circ}$
Relative lowering of vapour pressure
$\frac{P ^{\circ} - P}{P ^{\circ}} = x_{so l u t e}$
Elevation in boiling point
$Δ T_{b} = K_{b} m$
Depression in freezing point
$Δ T_{f} = K_{f} m$
Osmotic pressure
$π = C R T = \frac{n}{V} R T$
van't Hoff factor
$i = \frac{observed colligative property}{normal value}$
Colligative property with i
$Δ T_{b} = i K_{b} m, π = i C R T$
Degree of dissociation (from i)
$α = \frac{i - 1}{n - 1}$
Degree of association (from i)
$α = \frac{1 - i}{1 - \frac{1}{n}}$
Molar mass from ΔTb
$M = \frac{K _{b} \times w \times 1000}{Δ T _{b} \times W}$
Molar mass from π
$M = \frac{w R T}{π V}$
Henry's law
$p = K_{H} x$
Isotonic solutions
$π_{1} = π_{2} \Rightarrow C_{1} = C_{2}$
Ideal solution
$Δ H_{mi x} = 0, Δ V_{mi x} = 0$
Positive deviation
$P > P_{R a o u l t} (Δ H_{mi x} > 0)$
Negative deviation
$P < P_{R a o u l t} (Δ H_{mi x} < 0)$
ppm
$ppm = \frac{mass of solute}{mass of solution} \times 1 0^{6}$
Colligative property nature
$depends on number of particles, not identity$
