When two solvents are separated by a semi-permeable membrane, water flows from low solute concentrations to high solute concentrations. what would happen if external pressure is applied to the solution with higher solute concentration? a) the semi-permeable membrane will lose its activity. b) water will stop flowing across the semi-permeable membrane. c) water will flow more freely across the semi-permeable membrane. d) the concentration of solute will become equal on both sides of the membrane.

C) Water will flow more freely across the semi-permeable membrane.

Explanation:

Osmosis is the net movement of water molecules from an area of higher water concentration to that of lower water concentration.

Here in this case, an external pressure is applied to the solution with higher 'solute' concentration. If the pressure applied is greater than the osmotic pressure then the direction of water flow through the membrane would be reversed. Therefore, water molecules will flow from the high solute concentration to lower solute concentration.

The option C is the correct option.

Which is water will flow more freely across the semi-permeable membrane.
