Investigating the effect of sugar solutions on potato chips Aim In this investigation I will be finding out the effect of osmosis on potato chips at different concentrations of sucrose solutions. Prediction Osmosis is defined as the movement of water molecules across a partially permeable membrane from a region of high water concentration to a region of low water concentration. In a high concentration of water the amount of solute (e.g. sugar) is low. This could be called a weak or dilute solution. In a low concentration of water the amount of solute (e.g. sucrose) is high. This could be called a strong or concentrated solution. When two such solutions are divided by a semi-permeable membrane the water will move from the area of high concentration to the area of low concentration, until both sides are equal (have reached equilibrium). Weak solution partially permeable membrane Strong solution The solute molecule sugar is too...
