What would happen to an experiment if iodine was put in dialysis bag?

If iodine is placed in a dialysis bag, it will diffuse out of the bag into the surrounding solution, assuming the solution does not contain iodine. This is because the dialysis bag is typically permeable to small molecules like iodine, allowing it to move from an area of higher concentration (inside the bag) to lower concentration (outside). If the surrounding solution contains starch, a color change to blue-black will occur, indicating the presence of iodine, as iodine forms a complex with starch. If there is no starch, the iodine will simply diffuse into the solution without any observable reaction.
