  • Osmosis and Diffusion Via Dialysis Tube
    Open-ended Lab: Osmosis and Diffusion in Dialysis Tubing Name(s): Background: It is very difficult to measure or see osmosis actually occurring in cells because of the small size of most cells. However, if an artificial membrane that acts in some ways like a real plasma membrane could be found, than...

    Diffusion Osmosis Lab Report 1. Background - Osmosis is the movement of the water molecules from a region of higher water potential to a region of lower water potential - Water potential is a measure of the kinetic energy of water molecules. As water molecules are constantly moving in a random...

    Lab report OSMOSIS TROUGH A SELECTIVELY PERMEABLE MEMBRANE Introduction: Molecules have kinetic energy.  This causes the molecules of the cell to move around and bump into each other. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane (a membrane that...

  • Osmosis Lab Report
    Osmosis Lab Report Hypothesis: Osmosis will occur when there is an uneven distribution of solute in a solvent. The higher the solute in solvent, then there will be a higher rate of osmosis through the diffusion gradient forming a hypertonic or hypotonic solution. Solvent with equal or no solute forms...
