Introduction I have been asked to investigate the effect of changing the concentration of a solution on the movement of water into and out of potato cells. I will be able to change the input of my experiment. The input variable will be the concentration of the solution. The 100% solution is sodium chloride dissolved in water (salt water). This will be referred to as the 100% solution from now on. But the type of solution is not important as Osmosis is all about differences in concentrations. The output variable will be the weight of the potato chips, the movement of the water into and out of the potato. Osmosis is the diffusion of water through a semi-permeable membrane from high concentration of water to a low concentration of water. The water molecules move freely through the semi-permeable membrane this is a passive process. We will do this experiment by placing...
