In the lab, you use a special balloon that is permeable to water but not sucrose to make an "artificial cell." The balloon is filled with a solution of 20% sucrose and 80% water and is immersed in a beaker containing a solution of 40% sucrose and 60% water. The solution in the balloon is ________ relative to the solution in the beaker.
A) isotonic
B) hypotonic
C) hypertonic

Question

Quizplus · Accepted Answer

Since the balloon is permeable to water but not to sucrose, water will move from the side of lower solute concentration (the beaker) to the side of higher solute concentration (the balloon) through a process known as osmosis. The 20% sucrose solution in the balloon is less concentrated than the 40% sucrose solution in the beaker. Therefore, the solution in the balloon is hypotonic relative to the solution in the beaker.
