Question: For which molecules and ions (phenolphthalien,iodine, starch, na+,oh-, water) does your experiment give evidence for passage through the semipermeable dialysos membrane? in which direction(into or out of the bag) are the molecules moving?
Question: What characteristics was different in those molecules and ions passing through the membrane from those that did not pass through the membrane in this experiment?
Question: What properties of a molecule would make it unable to pass through a real ceall's lipid bilayer? what properties of the liquid bilayer make this happen?
