Two solutions with concentrations of 2% sugar and 4% sugar, respectively, are separated by a semipermeable membrane. During osmosis, there is a net flow of
A)sugar molecules from the concentrated to the dilute solution.
B)sugar molecules from the dilute to the concentrated solution.
C)water molecules from the concentrated to the dilute solution.
D)water molecules from the dilute to the concentrated solution.

Question

Quizplus · Accepted Answer

During osmosis, water molecules move from the solution with a lower concentration of solute (in this case, sugar) to the solution with a higher concentration of solute, across a semipermeable membrane. This means water moves from the 2% sugar solution to the 4% sugar solution.
