Answer:
c. The starch stayed in the bag and the iodine leaked into the bag and the reacted with it, turning the solution black.
Explanation:
According to the given information, the solution inside the dialysis tubing has starch while water present outside has iodine. The color of the water present outside the dialysis tubing does not change which means that starch did not leak out of the bag and stayed in the bag itself. On the other hand, the starch solution present inside the bag turned black representing the fact that iodine entered the bag. The reaction of starch with iodine produces a blue-black color.
