Calculate osmotic pressure using concentration, temperature, and van't Hoff factor.
Calculate solution concentration from osmotic pressure measurements.
Calculate molecular weight using osmotic pressure measurements.
Osmotic pressure (π) is the minimum pressure needed to prevent the flow of solvent across a semipermeable membrane. It's a colligative property that depends on the number of dissolved particles.
π = MRT
Where:
The van't Hoff factor (i) accounts for ionic dissociation:
Osmotic pressure is crucial in:
Understanding osmotic pressure is vital for:
π = iMRT
M = (gRT)/(VπM)
M = π/(iRT)
