Question

sis bags, constructed from a semipermeable membrane that is impermeable to sucrose, were tions of sucrose and then placed in separate beakers containing an initial concentration of 0.6 M sucrose filled with various e intervals, the bags were massed (weighed) and the percent change in mass of each bag was grap solution. At hed. 10 20 30 40 50 60 Time (minutes) h line in the graph represents the bag that contained a solution isotonic to the 0.6 M solution at 35) the beginning of the experiment? E) E D) D A) A B) B C)C

Explanation / Answer

Answer: Line C represents the bag that contain a isotonic to the 0.6 M solution. because the fluid movement is uniform or static, and equillibrium is maintained by the bag. nothing is going in or out. thats why the graph is flat.
