when two chambers are separated by a membrane permeable to water but not solute, if water is free to move in either direction without limitation or pressure, then water will
move from the chamber with the higher solute concentration to the chamber with the lower solute concentration. This is known as osmosis.
When two chambers are separated by a membrane that is permeable to water but not solute, a process called osmosis occurs. In this case, water will move from an area of lower solute concentration to an area of higher solute concentration until the solute concentrations on both sides of the membrane are equal.
To understand why water moves in this way, we need to consider the concept of osmotic pressure. Osmotic pressure is the pressure required to prevent the flow of water across a semipermeable membrane. It is directly proportional to the solute concentration and inversely proportional to the volume of water.
In your scenario, the membrane is selectively permeable to water but not solute, meaning that only water molecules can pass through. If the solute concentration is higher on one side of the membrane than the other, there will be a difference in osmotic pressure.
Since water moves from areas of lower osmotic pressure to higher osmotic pressure, it will move from the side with lower solute concentration to the side with higher solute concentration. This process will continue until the solute concentration is equal on both sides, and the osmotic pressures are balanced.
Therefore, in the given scenario, water will move from the side with lower solute concentration to the side with higher solute concentration until an equilibrium is reached.
When two chambers are separated by a membrane that is permeable to water but not solute, and water is free to move in either direction without limitation or pressure, then water will undergo a process called osmosis.
Osmosis is the movement of solvent molecules (in this case, water) from an area of lower solute concentration to an area of higher solute concentration through a selectively permeable membrane. The solute molecules cannot pass through the membrane, but water molecules can.
In this scenario, water molecules will move from the side with lower solute concentration to the side with higher solute concentration until equilibrium is reached. This means that the concentration of solutes will become equal on both sides of the membrane.
So, in summary, if water is free to move without limitation or pressure across a membrane permeable to water but not solute, it will move through the membrane via osmosis from an area of lower solute concentration to an area of higher solute concentration until equilibrium is achieved.
