Rate of Osmosis on Potato Chips Rate of Osmosis on Potato Chips Planning We have been asked to investigate the effect of osmosis on potato chips. Osmosis is the diffusion of water from a lower concentration of solute to a higher concentration of solute, through a membrane. I have chosen to investigate the effect of the water potential/concentration of solution on potato chips. This means that I will put potato chips into salt solutions of different concentrations. These concentrations would be ones such as these; 0.25mola, 0.5m, 0.75m, 1.0m, 1.25m, 1.50 and distilled water. There are other factors involved and these are; ¨ Temperature ¨ Water potential of potato initially ¨ SIZE of potato ¨ Light intensity ¨ Mass of potato dependent variable ¨ Volume of solution potato chip is in ¨ Type of potato ¨ Time left in solution ¨ Surface area of potato chip ¨ Use the same balance to measure chip If I am going to conduct a fair test, then I am going to have to control these other factors. Doing all the tests at one temperature will control the temperature. For the purpose of my experiment I am going to do all the experiments at room temperature. To keep the water potential of the potato initially will be kept the same by mass, potato, chip, water, solution, results, same, each, because, change, experiment, chips, osmosis, attempt, graph, average, after, out, must, test, kept, going, concentration, salt, cut, before, potential, make, am, through, potatoes, %change, tubes, take, size
