Which starch solution will decrease in volume as osmosis occurs?
A)4%
B)10%
C)Neither exerts osmotic pressure.
D)They exert equal osmotic pressures.
E)They exert opposite osmotic pressures.

Question

The lower the concentration of the solution, the higher the osmotic pressure. Therefore, the 4% starch solution will exert a higher osmotic pressure than the 10% starch solution, resulting in a decrease in volume as water moves from the higher concentration of water outside the membrane to the lower concentration of water inside the membrane. Choice B is incorrect because the 10% starch solution has a higher concentration and will increase in volume as osmosis occurs. Choice C is incorrect because both solutions will exert osmotic pressure; it's just that the 4% starch solution will exert more pressure. Choice D is incorrect because the two solutions will exert different osmotic pressures. Choice E is also incorrect because the two solutions will not exert opposite osmotic pressures.
