... taken place from the potato tube into the sucrose solution. This has helped me to show that there will be differences in mass, but it doesn't tell me that there will be differences in changes with lower Molarity solutions or higher Molarity solutions. Theory I am testing to see whether potato tubes will gain in mass and size in water, and I will also see whether the Molarity of the solution that the tubes are placed in will effect the mass and size difference. I am doing this because osmosis is the diffusion water particles from a dilute solution to a concentrated solution. The varying Molarity solutions will effect how much dilute solution will diffuse into the concentrated solution. I will base this hypothesis on a preliminary experiment done before. The results showed that the potatoes lost mass in a sucrose solution and gained mass in water. This is because the water ...
