Osmosis Coursework - Osmosis with Potato Chips Aim: To investigate the effect of concentration on the amount of osmotic activity between the solution and a potato chip of a fixed size. Prediction: Osmosis is the net movement of water molecules from a place where they are in a higher concentration to a place where the water molecules are in a lower concentration, through a partially permeable membrane such as a cell wall, which lets smaller molecules such as water through but does not allow bigger molecules such as salt to pass through. This occurs down a concentration gradient. The molecules will continue to diffuse until the area in which they are found reaches a state of equilibrium, which means that the molecules are randomly distributed throughout an object, with no area having a higher or lower concentration than any other. For this particular investigation I predict that the lower the concentration of the...
