In the lab, you use a special balloon that is permeable to water but not sucrose to make an "artificial cell." The balloon is fi
lled with a solution of 20% sucrose and 80% water and is immersed in a beaker containing a solution of 40% sucrose and 60% water.Which of the folloing will occur?A. water will enter the balloonB. water will leave the balloonC. sucrose will enter the balloonD. sucrose will leave the balloonE. none of the choices will occur
The correct answer is B. water will leave the balloon.
Explanation:
As the sucrose concentration is higher in the solution, the water in the balloon, where the sucrose is less concentrated, will tend to leave and try to dilute the outer solution until both sucrose concentrations are equal. But as the water leaves the balloon, the concentration inside will increase, so it will flow outside until both concentrations are equal and not until the outer concentration is similar to the initial concentration in the balloon.
