Sucrose And Water Affect The Rate Of Osmosis

This experiment was conducted in order to discover whether different solute concentrations of sucrose and water would affect the rate at which osmosis would occur. The dialysis tubing represented the semi-permeable membrane and the concentrations of solution represented the cytoplasm. Through the observations made during the experiment it is clear to see that the rate of osmosis was affected by the different solution concentrations that were used. The way in which the rate of osmosis was affected was that with more high solution concentrations (less water) the rate at which water particles are able to move through the dialysis tubing increases. The lower the concentration the more slowly the water particles are able to diffuse. Through our findings (Table1.0) and the determined rates of osmosis, it is clear to see that the higher the concentration solution the more…show more content…
When the dialysis is placed within the hypotonic (high water) environment of the beaker, the water attempts to move through the semi-permeable membrane to the hypertonic solution of sucrose (low water). This can be determined through the results that were gathered in Table 1.0. The higher concentrations of sucrose resulted in quicker rates of osmosis and also an increase in mass. This increase in mass can be attributed to the water from the hypotonic solution that through the process of osmosis transferred into the dialysis tubing. However there was not an equal transfer of molecules since the sucrose solute from the concentrations was unable to make it through the membrane. The reason that the mass did not simply stay the same and the transfer of molecules was not equal, was because the dialysis tubing allows for the flow of water molecules through the membrane but not sucrose molecules. The pores on the tubing are only large enough to allow for a water molecule to pass through but, not the sucrose
