  1. Osmosis Notes

  2. Answer the following: • You have two containers, one containing 100ml of pure water and 100 ml of salt water? In which container do you have more water? Explain • You have more water in the 100 ml of pure water because some of the volume of the 100ml of salt water is taken up by the NaCl and not all H20

  3. Osmosis: Diffusion of water through the membrane Factors that determine how the water will move across the membrane: Amount of solute inside the membrane Amount of solute outside the membrane

  4. Is there an equal amount of water on both sides of the membrane? Higher amount of solutes outside the cell Lower amount of solutes inside the cell

  6. Three Cell Osmotic Environments Equal solutes on both sides of the membrane. Equal amounts of water on both sides of the membrane No net movement of water Less solute outside the membrane(more water) More solute inside the membrane(less water) Water will move IN to maintain water balance More solute outside the membrane(less water) Less solute inside the membrane(more water) Water will move OUT to maintain water balance
