A semipermeable membrane is placed between the following solutions.
Which solution will increase in volume?
A
Solution A: 6.78% NaCl
B
Solution B: 12.7% NaCl
검증된 단계별 안내1
Identify the nature of the membrane: It is semipermeable, meaning it allows the solvent (usually water) to pass through but not the solute (NaCl in this case).
Compare the concentrations of NaCl in the two solutions: Solution A has 6.78% NaCl, and Solution B has 12.7% NaCl, so Solution B is more concentrated.
Understand osmosis: Water will move from the side with lower solute concentration (Solution A) to the side with higher solute concentration (Solution B) to try to equalize the solute concentrations on both sides.
Predict volume changes: Because water moves into Solution B, its volume will increase, while the volume of Solution A will decrease.
Conclude that Solution B will increase in volume due to the osmotic flow of water through the semipermeable membrane.
