Sheena Shah 11AL Osmosis in a Potato Chip Aim: An investigation into osmosis using a pealed potato and different concentrations of salt solution. Hypothesis: I predict that in this experiment, a higher concentration of salt solution will move to an area of low concentration of a solution. The definition of osmosis that the CGP Science Book gives is "Osmosis is the movement of water molecules across a partially permeable membrane from a region of high water concentration to a region of low water concentration." This means that if the potato is surrounded by a solution, which has a low concentration, the mass of the potato will decrease, as the high concentration from the potato will move onto the water, there for increasing the volume of water surrounding the potato. The partially permeable membrane in this experiment is the surfaces of the pealed potato. It will let the salt solution pass in and out of...
