Question

I take a bag made of dialysis tubing (a semipermeable membrane that is permeable to water and glucose, but not starch). Inside it, I pour a 5M starch solution.I place it in a big container full of 5M Glucose solution.What do you expect will happen to the glucose, starch and water?

Answer 1

In this experiment, the dialysis tubing bag will allow water and glucose molecules to diffuse through, but not starch. Therefore, the water and glucose will move into the bag, while the starch will remain inside.

Step-by-step explanation:

In the given experiment, a bag made of dialysis tubing is filled with a 5M starch solution and placed in a container of 5M glucose solution. Since the dialysis tubing is permeable to water and glucose, but not starch, the water and glucose molecules will diffuse through the tubing into the bag, while the starch molecules will remain inside the bag. As a result, the concentration of glucose inside the bag will increase, while the concentration of glucose in the container will decrease. The concentration of starch will remain the same inside the bag.
