Two containers of equal volume are separated by a membrane that allows free passage of water but completely restricts passae of solute molecules. Into which compartment will water flow, or will there be no net movement of water? Which solution is at the higher concentration? Which chamber is exerting the higher osmotic pressure?
See your dupliate post.
In this scenario, we have two containers of equal volume separated by a membrane. The membrane allows free passage of water but does not allow the passage of solute molecules.
If there is a difference in solute concentration between the two compartments, the water will move by osmosis towards the chamber with the higher solute concentration. This movement of water will continue until the solute concentrations become equal or until the pressure exerted by the movement of water opposes further water movement.
Therefore, water will flow into the compartment with the higher solute concentration, and the solution in that chamber is considered to have a higher concentration. The chamber with the higher solute concentration will also exert a higher osmotic pressure due to the movement of water into that compartment.
To determine the direction of water flow, the relative concentrations of solute molecules in the two compartments should be considered. Water has a tendency to move from an area of lower solute concentration to an area of higher solute concentration. This movement is driven by osmosis.
In this scenario, let's assume that one compartment contains a solution with a higher concentration of solute molecules compared to the other compartment. Since the membrane allows free passage of water but not solute molecules, water will flow from the compartment with lower solute concentration to the compartment with higher solute concentration.
Therefore, water will flow into the compartment that has a higher concentration of solute molecules. This process will continue until the solute concentrations in both compartments become equal or reach equilibrium.
Regarding the chamber with higher concentration, it will be the one where water is flowing into. This chamber will have a higher concentration of solute molecules, compared to the other chamber from where water is flowing out.
Lastly, the chamber with water flowing into it will exert the higher osmotic pressure. Osmotic pressure is the pressure required to prevent the net movement of water across a semipermeable membrane. Since water is moving into this chamber, there is a higher tendency for water to pass through the membrane, resulting in a higher osmotic pressure in that chamber.
