PLANNING Aim: * I want to find out how the concentration of a sucrose solution affects the mass of several pieces of potato in different molarities, through the process of Osmosis. * Osmosis is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration. Factors: * Temperature: This may affect the rate of osmosis as water moves quicker when warmed causing the rate of osmosis to increase. Likewise if the water is cooled the water will move slower so the rate of the movement of water will decrease. * The surface area of Potato: The rate of osmosis may be affected as the bigger the surface area, the more likely water will move through the selectively permeable membrane, as there are more holes in the membrane for it to pass through. Whereas a small surface area will less likely allow water to move...
