If two solutions having different osmolarities are separated by a water-permeable membrane will there be a change in the volume of the two compartments if the membrane is impermeable to solutes?

Answer 1

Water will flow from a region of higher concentration to lower concentration until the two osmolarities are equal if the membrane is impermeable to the solute. A change in the volume of the solution would be the result. If it is permeable then the solute will diffuse simultaneously from the higher solution to the lower solution until equilibrium is reached. The volume will not change in this case.

Answer 2

An ionic compound when put into an semipermeable membrane breaks apart/ dissociates into how many pieces?...Two solutions can have the same molality, meaning the elements on the Periodic Table are equal to one mole, and if they have the same solution like 1 liter, then grams cancels out and you are left with one mole. So lets say we are working with Na Cl and glucose they can have the same molality but have different osmolality because Na Cl breaks off into 2, and glucose C6H1206 dissolves but does not dissociate it remains intact in 1 piece. Now the osmolality is higher for sodium chloride vs glucose.

Answer 3

If two compartments separated by a semi-permeable membrane, there will be a shift of water from low solute concentration to high concentration. This will lead to a change in volume from the low concentration side to the high concentration side.

Answer 4

If two solutions of differing solute concentration (molarities) are separated by a water permeable membrane, diffusion will occur. In this case water molecules will diffuse across the membrane from the area of low solute concentration to the area of high solute concentration.

Answer 5

Yes, there will be a change in volume as water will move across the membrane from the side with lower osmolarity to the side with higher osmolarity through the process of osmosis. This will cause a volume increase in the compartment with higher osmolarity and a volume decrease in the compartment with lower osmolarity.

Answer 6

water will move across the membrane by osmosis

Answer 7

Water molecules move between the two solutions, but there is no net movement of water across the membrane
