b. Aces the plastic bag was permeable to iodine.
c. The iodine moved into the plastic bag.
d. The cornstarch moved into the beaker.
e. The plastic bag was selectively permeable.
The solution in the dialysis tubing bag turning dark purple indicates that the iodine has moved into the bag and reacted with the cornstarch. This means that options (b) and (c) are correct.
The dialysis tubing bag is selectively permeable, which means that it allows certain molecules to pass through while blocking others. In this case, the bag is permeable to iodine molecules, but not to larger molecules such as cornstarch. Therefore, option (e) is also correct. The cornstarch did not move into the beaker, as the bag is designed to keep its contents inside. Therefore, option (d) is incorrect. The fact that the solution in the bag turned purple indicates that the bag was permeable to cornstarch, as it allowed the iodine to come into contact with the cornstarch and produce the purple color. Therefore, option (a) is also correct.
Because the solution in the bag turned purple as a result of the iodine's contact with the cornflour, it can be concluded that the bag was permeable to cornflour. This contact enabled the purple colour to be produced. As a result, choice (a) is also accurate.
