Figure 5.4
-Five dialysis bags,constructed from a semipermeable 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.Figure 5.4 illustrates the change in the mass of the bags over time.Which line in the graph represents the bag with the highest initial concentration of sucrose?

Question

Quizplus · Accepted Answer

The bag with the highest initial concentration of sucrose would gain mass if placed in a solution with a lower concentration of sucrose due to osmosis. Line A shows the greatest increase in mass, indicating it started with the highest concentration of sucrose, as water moved into the bag to balance the concentration gradient.
