Question

1. five dialysis bags, constructed of a type of membrane that 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. which line in the graph represents the bag with the highest initial concentration of sucrose? a) a b) b c) c d) d

Explanation:

Step1: Understand osmosis principle

Osmosis is the movement of water across a semi - permeable membrane from an area of lower solute concentration to an area of higher solute concentration. The greater the initial solute concentration in the bag compared to the outside (0.6 M sucrose), the greater the initial influx of water and the steeper the initial increase in mass.

Step2: Analyze the graph

The line that starts with the steepest upward slope represents the bag with the highest initial concentration of sucrose as it will have the greatest initial water - influx. Line A has the steepest upward slope at the start.

Answer:

A. A
