Have a little read: ... In this investigation I am going to find out how a chip is affected by the concentration of the salt water, the length or width of the chip or the length of time the chip is in the solution for. Osmosis Osmosis is the movement of water through a selectively permeable membrane separating solutions of different concentrations. Water passes by diffusion from a weak solution (high water concentration) to a strong solution (low water concentration) until the two concentrations are equal. The selectively permeable membrane allows diffusion of water but not of the solute. The level of liquid in the tube of sugar solution will eventually rise until the flow of water from the tube of sugar solution, under the influence of hydrostatic pressure, equals the flow of water into the tube. The hydrostatic pressure establishing this equality of flow is called osmotic pressure. A variety of physical and chemical principles
