Osmosis Coursework My Prediction Osmosis the the movement of water molecules which pass through a partially permeable membrane from an area of high water potential to an area of low water potential. Therefore, ina high concentration of NaCl, the water will move out of the potato causing it to shrink. In low The larger the concentration of water in the outside of the solution the better the amount of water that enters the cell by osmosis. However, there will be a point where the concentrations of water inside and outside the potato cells are equal (isotonic). At this point there will be no change in the length, volume and mass of the potato, as the net movement of water will be zero, no osmosis has occurred. Using this information a graph and prediction can be made: Apparatus For the experiment I will need: 20 Cylinders of potato , diameter 0.5 mm Cork Borer Nacl solution: o.25m, 0.5m,...
