Osmosis and diffusion coursework
Osmosis is the best way to perform this experiment because as we went through the experiment, the weight of the beaker/dialysis tubing changed and the only logical explanation was that diffusion of water had occurred. They will observe the processes of diffusion and osmosis, first in two teacher-led demonstrations, and then through two lab activities: the diffusion of starch molecules through a plastic bag and potato cores immersed in isotonic, hypotonic, and hypertonic solutions. Osmosis is the diffusion of water through a selectively permeable membrane from an area of low solute/high water concentration (hypotonic) to an area of high solute/low water concentration (hypersonic). Osmosis is the result of diffusion across a semipermeable membrane if two solutions of different concentration are separated by a semipermeable membrane, then the solvent will tend to diffuse across the membrane from the less concentrated to the more concentrated solution this process is called .
