Preliminary Experiment Aim The aim of this experiment is to determine the solute concentration of potato tissue; i.e. To investigate at which point the sucrose concentration is the same as the solute concentration inside the potato (an equilibrium is reached) Introduction Osmosis is the movement of water molecules from an area of high concentration; (a weak solution), to an area of low concentration; (a strong solution), through a partially permeable membrane. My experiment will prove that the concentration inside the potato is lower than the concentration of the water molecules, outside the potato if using distilled water or very low concentrations of sucrose solution. Preliminary Method Cut two potato cylinders to the correct sizes e.g. 5cm in length, and dry them out using paper towels. It is important to dry out the potato cylinders because the excess water inside would have an effect on the results, and this would therefore create an unfair experiment. Then...
