INVESTIGATING THE MOLARITY OF A SOLUTION IN WHICH A POTATOE CYLINDER DOES NOT CHANGE IN LENGTH OR MASS Introduction My aim of this investigation is to find out when the molarity of a solution results in a potato cylinder neither changing in mass or weight. To do this I will place a potato cylinder in water to allow osmosis to take place. If I used just a test tube of pure water there is a different concentration of water inside the potato compared to outside, therefore osmosis will take place. In this case, the tiny holes in the membrane of the potatoes will allow the water molecules to pass through in and out of the solution and the potato. I am going to investigate changing the molarity of solution outside the potato cylinder so that the concentration of water inside the potato and outside the potato are the same, therefore osmosis...
