Fifty percent dextrose solution is placed on side A of a membrane, and 25 percent dextrose is placed on side B of a membrane. Assuming the membrane is permeable to water, but not solutes, what will happen?
A) Water may move freely in both directions, but there will be no net movement of water.
B) Net movement of water from side B to side A will occur.
C) Net movement of water from side A to side B will occur.
D) Water will not move in either direction.

Water moves from areas of lower solute concentration to areas of higher solute concentration to achieve equilibrium when a membrane is permeable to water but not to solutes. Therefore, water will move from side B (25% dextrose) to side A (50% dextrose) to balance the concentration difference.
