Question

The solution that exerts highest osmotic pressure is________.

Answer 1

Osmotic Pressure:

1. The equation to calculate osmotic pressure is: π=iCRT where, π= osmotic pressure of the solution, i= Van't Hoff factor = 1 (for non-electrolytes), R= Gas constant, T= temperature of the solution
2. As per the definition "Osmotic pressure is the minimum pressure that must be applied to a solution to avoid the movement of solvent molecules across a semipermeable membrane".
3. This is a colligative property that is by definition affected by the solute particle concentration in the solution.

Final answer: The solution that exerts the highest osmotic pressure is the solution with the highest concentration of colligative ions.
