Investigating Osmosis in potatoes. Aim: To investigate how the concentration of different sugar solutions affects osmosis through a semi-permeable membrane in potato chips. Prediction: I predict that the potato chip in the solution with the greatest osmotic concentration will gain water, as there will be a higher concentration of sugar inside the potato than outside therefore it will need to balance out. Whereas the potato chip in the solution with the lowest osmotic concentration will lose water, as there will be a higher concentration of sugar outside the potato. This is all due to a process known as osmosis. Osmosis is the net movement of solvent molecules from a region of high concentration to a region of low concentration through a semi-permeable membrane. A semi-permeable membrane only allows certain substances to pass through. For example, it will allow water molecules through but not salt molecules. The process of osmosis works as follows: Plants...
