Osmosis in potato cores
|
|
|
The results of this lab where quite what one would expect. The lower the molage of the sucrose concentration, the more the potato grew in mass. For an extreme example take the final results of the distilled water and the 1 M of sucrose solution. The % in weight change for the 1M of sucrose concentration was -12.5 which was over all the highest change, and the least mass left in the potato cores. The opposite was true for the potato cores in the distilled water. In the end they grew by 5.7%, the highest positive weight change. The results for the sucrose concentrations in between fall nicely into place and clearly show that as the sucrose concentration was higher the hypertonic the potato cells became, where as when the concentration was lower the potato cells became more hypotonic. A graph of the total percent weight change against sucrose concentration shows that at .28M sucrose concentration would be isotonic to the potato cells, meaning that with that concentration osmosis would not take place because they would both have the same concentration.
