Elena Uteva Investigating the factors that affect osmosis in a model potato cell Introduction In the following investigation, I shall explore and come to a conclusion on the effect of varying the concentration of the surrounding sucrose solution on a model potato cell. Osmosis is defined as the passage of water molecules through a selectively permeable membrane from a region of high water concentration to a region of low water concentration until a state of equilibrium is reached. The selectively permeable membrane is permeable to the solvent and not to the solute and therefore results in a pressure gradient across the membrane. My hypothesis regarding this investigation is that an increase in the concentration of the sucrose solution will decrease the mass of the potato chip. This is because a higher solute concentration will result in lower water concentration, since by increasing the solute concentration there would be more solute...
