Read the following information and refer to Figure 7.4 to answer the following questions.
Five dialysis bags, constructed from a semi-permeable membrane that is impermeable to sucrose, were filled with various concentrations of sucrose and then placed in separate beakers containing an initial concentration of 0.6 M sucrose solution. At 10-minute intervals, the bags were massed (weighed) and the percent change in mass of each bag was graphed.

-Which line or lines represent(s)bags that contain a solution that is hypertonic at the end of 60 minutes?
A)A and B
B)B
C)C
D)D
E)D and E

Quizplus · Accepted Answer

Bag B is the only bag that shows a decrease in percent change in mass over the 60-minute period, indicating that it contains a hypertonic solution at the end of 60 minutes. The other bags either show no change or an increase in percent change in mass, indicating isotonic or hypotonic solutions.
