Question
Five dialysis bags constructed of membrane, which is permeable to water and 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. 10 20 30 40 50 60 Time (minutes) Which line in the graph represents the bag that contained a solution isotonic to the 06 M solution at the beginning of the experiment? ?) ?
Explanation / Answer
ANSWER IS: C
EXPLANATION:
Isotonic solution defined as same concentration of solutes across a semipermeable membrane.
Straight line in the graph represents isotonic solution as straight line shows same concentration and shows no change.
