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.
The solution in the berzelius glass has a concentration of 50%, the other solution has a concentration of 30%. In osmosis water moves from the solution with a lower concentration to the solution with the higher concentration. Therefore, water will move from the 5%glucose,25%starch solution to the 20%glucose, 20%K⁺,10% iodine.
