A dialysis sac that is permeable to glucose and water is filled with water and placed in a beaker containing 20% glucose solution. Will there be a net transport of water across the dialysis sac? If so, in which direction will the water move, into the sac or out of the sac?

Question

Quizplus · Accepted Answer

Water will move out of the sac due to osmosis, as it moves from an area of lower solute concentration (inside the sac) to an area of higher solute concentration (outside in the 20% glucose solution).
