A solvent and its solution containing a nonvolatile solute are separated by a semipermable membrane. Does the flow of solvent occur in both directions? Comment giving reason. ki |

Answer» 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] |
