Consider pure water separated from an aqueous sugar solution by a semipermeable membrane,which allows water to pass freely but not sugar.After some time has passed,the concentration of sugar solution:
A)will have increased
B)will have decreased
C)will not have changed
D)might have increased or decreased depending on other factors
E)will be the same on both sides of the membrane

Question

Quizplus · Accepted Answer

The process that occurs in this scenario is osmosis. As pure water passes through the semipermeable membrane into the sugar solution, the concentration of water on the side with the sugar solution decreases. As a result, the concentration of sugar in the solution will become more concentrated, leading to an increase in the concentration of sugar on that side. Therefore, choice B, which states that the concentration of sugar solution will decrease, is the correct answer.
