A selectively permeable membrane separates two solutions. Water is able to pass through this membrane; however, sucrose (a disaccharide) and glucose (a monosaccharide) cannot pass. The membrane separates a 0.2-molar sucrose solution from a 0.2-molar glucose solution. With time, how will the solutions change?
A
Water will enter the sucrose solution because the sucrose molecule is a disaccharide and, thus, larger than the monosaccharide glucose.
B
Water will leave the sucrose solution because the sucrose molecule is a disaccharide and, thus, larger than the monosaccharide glucose.
C
The sucrose solution is hypertonic and will gain water because the total mass of sucrose is greater than that of glucose.
D
After the sucrose dissociates into two monosaccharides, water will move via osmosis to the side of the membrane that contains the dissociated sucrose.
E
Nothing will happen because the two solutions are isotonic.
Verified step by step guidance1
Understand the concept of osmosis: Osmosis is the movement of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
Identify the solute concentrations: Both solutions have a 0.2-molar concentration, meaning they have the same concentration of solute particles.
Recognize the nature of the membrane: The membrane is selectively permeable, allowing water to pass through but not sucrose or glucose.
Determine the tonicity of the solutions: Since both solutions have the same molarity, they are isotonic, meaning there is no net movement of water across the membrane.
Conclude the effect on the solutions: Because the solutions are isotonic, there will be no change in the volume of either solution over time due to osmosis.
