  • Osmosis Potato practical

    1. Peel off potato skin
    2. Cut 6 pieces of potato same diameter
    3. Blot each piece of potato with a paper towel
    4. Record mass of each potato
    5. Pour 10cm^3 of 0.5 mol/dm^3 sugar solution into a boiling tube
    6. Repeat for each mol/dm^3 sugar solution (0,1,2,3,4,5)
    7. Place 6 potatoes into each boiling tube
    8. Remove potatoes from solutions after 24 hours
    9. Record final mass of potato and calculate the change in mass
    10. Plot results in a table
  • Higher the sugar solution

    More water lost by osmosis
  • Water only in the tube

    It will grow by length by osmosis - the movement of water from a high water concentration to a low water concentration
