Question

A solvent and its solution containing

a nonvolatile solute are separated by

a semipermable membrane. Does the

flow of solvent occur in both directions?

Answer 1

$\huge\text{</strong><strong>Answer</strong><strong>}$

Osmotic Pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane.[1] It is also defined as the measure of the tendency of a solution to take in pure solvent by osmosis. Potential osmotic pressure is the maximum osmotic pressure that could develop in a solution if it were separated from its pure solvent by a semipermeable membrane.

Osmosis occurs when two solutions containing different concentrations of solute are separated by a selectively permeable membrane. Solvent molecules pass preferentially through the membrane from the low-concentration solution to the solution with higher solute concentration. The transfer of solvent molecules will continue until equilibrium is attained.[1][2]

Answer 2

Osmotic pressure is the tendency of solvent molecules to move in the direction of lower solvent activity. It plays a central role in biology
