Question

See figure: The U-shaped tube is divided by a membrane that is impermeable to galactose but permeable to water. The liquid volume of left side will ________ after 1 hour.

Answer 1

We have two solutions of galactose, one at 5% and another at 11%, given that the 11% solution is hypertonic to the 5% solution, which means water will flow to the right side of the tube. This means that after 1 hour, the volume on the left side of the tube would decrease.
