Relation Between Osmotic Pressure and Relative Lowering of Vapour Pressure :

Relation between Osmotic Pressure and other Colligative Properties Chemistry Notes 1

Where, \(\mathrm{p}_{\mathrm{A}}^{0}\) = Partial vapour pressure of pure solvent
PA = Vapour pressure of solution
d = Density
R = Gas constant
T = Temperature
MB = Molar mass of solute

Relation between Osmotic Pressure and Elevation of Boiling Point

π = ∆Tb × \(\frac{d R T}{1000 \times K_{b}}\)
∆TB = Elevation in boiling point
d = Density
R = Gas constant
T = Temperature
Kb = Molal elevation constant

Relation between Osmotic Pressure and other Colligative Properties Chemistry Notes

Relation between Osmotio Pressure and Depression in Freezing Point :

π = ∆Tf × \(\frac{\mathrm{d} \mathrm{RT}}{1000 \times \mathrm{K}_{\mathrm{f}}}\)
Where Tf = Depression in frezing point
d = Density
R = Gas constant
Kf = Molal depression constant
T = Temperature (in kelvin, ‘K)
π = Osmotic pressure
