WebWhy or why not? ” starch molecules did not diffuse out of the dialysis bag because they are too big to pass through the pores of the dialysis tubing Experiment 3: Osmosis - Direction and Concentration Gradients ” Hypothesis: ” There will be a greater net displacement for the band color solutions with a higher percentage of sucrose. 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.
