An Experiment to investigate the mass and surface area of potato chips after being in different concentrations of NaCl. * I predict that the percentage decrease in mass and surface area of the potato chips will decrease more as the percentage of NaCl is increased. -This is because the NaCl solution has a higher concentration and lower water potential than the potato, which has a low concentration and high water potential. Therefore I predict osmosis will occur. I define Osmosis as the movement of any solution's molecules from a place where they are highly concentrated to a region where they are in lower concentration. These molecules must pass through a semi permeable membrane (in this case the cell wall), which lets through smaller molecules but not larger ones. So water molecules from the potato will pass through the cell wall to the NaCl solution. My prediction will only be correct if...
