The minimum pressure that must be applied across the semipermeable membrane to obtain water has to be calculated. Concept Introduction: Osmotic pressure: The osmotic pressure of solution is defined as the difference in pressure needed for no net transfer of solvent to occur across a semipermeable membrane that separates the solution from the pure solvent. The osmotic pressure of a solution is proportional to the molar concentration of the solute particles in the solution and the equation is given by, Π=iMRT Here, Π= Osmotic pressure M= Molar concentration of the solute R= Ideal gas constant T= Temperature (in kelvins) i= van’t Hoff factor

Interpretation:

The minimum pressure that must be applied across the semipermeable membrane to obtain water has to be calculated.

Concept Introduction:

Osmotic pressure: The osmotic pressure of solution is defined as the difference in pressure needed for no net transfer of solvent to occur across a semipermeable membrane that separates the solution from the pure solvent. The osmotic pressure of a solution is proportional to the molar concentration of the solute particles in the solution and the equation is given by,

Π=iMRT

Here, Π= Osmotic pressure

M= Molar concentration of the solute

R= Ideal gas constant

T= Temperature (in kelvins)
