WebDialysis tubing (and most semi-permeable membranes) operate based on differences of size and not molecular weight. While the size of a molecule or ion does increase as its molecular weight increases, there is some nonintuitive size-mass discrepancies that can occur. Many of these discrepancies are well known to polymer chemists. WebDialysis tubing is used to simulate a cell membrane; it is permeable to small molecules and water, but not to larger molecules. Given the generally larger size of polysaccharides, it is hypothesized that starch will not pass through the dialysis tubing, and that iodine will pass through the membrane due to the small size of its molecules.
