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. flu is contagious for how many days

"WebThe Dialysis tubing provides a semi-permeable membrane. Only allowing smaller molecules to pass through it. Iodine molecules are small enough to pass freely through the membrane, however starch molecules are complex and too large to pass through the membrane. Initially there was a higher concentration of iodine outside than inside the tube. " - Can sugar pass through dialysis tubing

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.

WebThe dialysis tubing is selectively permeable because substances such as water, glucose, and iodine were able to pass through the tubing but the starch molecule was too large to pass. 3. Sucrose is a disaccharide and therefore much larger than the glucose, a monosaccharide, that was used in the experiment.
