Solute Concentration On Osmosis Experiment

This experiment determined how solute concentration affected the rate of osmosis in a cell and the outside environment. Three pieces of dialysis tubing were used as three different cells, each filled with different solute concentrations. Each one of the cells was placed in one of three beakers that were filled with tap water. The masses of each of these cells before being placed in the beakers, and afterwards in ten minute intervals for an hour. The percent difference between the initial mass and the mass at each of the ten minute intervals was calculated in order to show the results. The completion of the hour-long experiment showed that the higher the solute concentration, the higher the rate of osmosis, and that solute concentration is a major factor in the process of osmosis Introduction Osmosis is the diffusion of free water across a selectively permeable …show more content…
Each of the three cells had different initial masses, and it was difficult to get each of the cells to have a similar initial mass. This affected the data by causing the results in the table to appear skewed. In order to properly address this issue, one could measure out a specific amount of solution to be placed into the dialysis tubing at the beginning of the experiment, so the initial masses can be as close as possible. Solute concentration has a major effect on the rate of osmosis. How does temperature affect the rate of osmosis? In order to test this, one could add one to two drops of dye into boiling water, ice cold water, and room temperature water to observe the speed at which osmosis occurs in different temperatures. 300mL of boiling water, ice water, and room temperature water would each be placed into three beakers of the same size. One drop of 1% Brilliant Blue dye would be added to each of the beakers, and the time it takes for the dye to dissipate in each of the beaker would be measured and
