Can Iodine Diffuse Through A Selectively Permeable Membrane? Can iodine diffuse through a selectively permeable membrane? Starch does not pass through the synthetic selectively permeable membrane because starch molecules are too large to fit through the pores of the dialysis tubing. In contrast, glucose, iodine, and water molecules are small enough to pass through the
Did Starch Diffuse Through The Membrane? Did starch diffuse through the membrane? Starch does not pass through the synthetic selectively permeable membrane because starch molecules are too large to fit through the pores of the dialysis tubing.
