In the set-up shown in the figure below,which of the following statements would describe what would be observed after 12 hours of time have elapsed?
A) The level of the solution in the tube would rise because there are now more dissolved solutes present in the beaker than in the tube.
B) The level of the solution in the tube would lower because the glucose and salt would move into the tube.
C)The level of the solution in the tube would rise because there are now more dissolved solutes in the tube than the beaker.
D) The level of the solution would not change as the membrane prohibits any exchange between tube and the beaker.
E) The level of solution in the tubes would see no change because the solute levels are equal on both sides.

Quizplus · Accepted Answer

After 12 hours, osmosis would cause water to move from the beaker into the tube due to the higher concentration of solutes in the tube. This would cause the level of the solution in the tube to rise, making choice C the correct answer. Choice A is incorrect because there are actually more dissolved solutes in the tube than in the beaker. Choice B is incorrect because the glucose and salt would actually move into the tube, not out of it. Choice D is incorrect because while the membrane prohibits the movement of large molecules, it does allow for the movement of water molecules through osmosis. Choice E is incorrect because the solute levels are not equal on both sides, as there are more solutes in the tube.
