Amy Grammer 11.6 AT1 Aim: - To investigate the effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and the potato chip. Background information If a dilute solution is separated from a concentrated solution by a partially permeable membrane, water diffuses across the membrane from the dilute to the concentrated solution. This is known as Osmosis. A partially permeable membrane is porous but allows water to pass through more rapidly than dissolved substances. Since a dilute solution contains, in effect, more water molecules than a concentrated solution, there is a diffusion gradient that favours the passage of water from the dilute to the concentrated solution. In living cells, the cell membrane is partially permeable and the cytoplasm and vacuole (in plant cells) contain dissolved substances. As a consequence, water tends to diffuse into cells by Osmosis if they are surrounded by a weak solution, e.g. fresh...
