• Osmosis and the Visking Tubing
    Osmosis is the net movement of water from a high concentration of water to a low concentration of water down a concentration gradient. This is done to equalise the solute concentrations on the two sides. Therefore, in other words, the movement of water is depended on the concentration of dissolved solute...

    inside the cells had a higher solute concentration (and therefore less water) than the surrounding solution. As a result, water moved into the cells by osmosis, resulting in an increase in mass. In the model cells placed in the 6% and 8% sodium chloride solutions, the mass of the cells decreased. This...
