Abstract:
The purpose of this experiment was to investigate the process of osmosis using potatoes and different salt solutions. Osmosis is the movement of water molecules across a selectively permeable membrane from an area of high water concentration to an area of low water concentration. In this experiment, potato slices were placed in different salt solutions with varying concentrations to observe the effects of osmosis on the potatoes.
The results of the experiment showed that the potato slices in the higher concentration salt solutions lost more water and shriveled up, while the potato slices in the lower concentration salt solutions gained water and swelled up. This demonstrates the process of osmosis, where water moves from an area of high concentration to an area of low concentration to equalize the solute concentrations on both sides of the membrane.
Overall, this experiment successfully demonstrated the process of osmosis using potatoes and salt solutions. Further studies could explore the effects of different solutes on osmosis and investigate how osmosis can be applied in various biological and industrial processes.

Title: The Effect of Salt Concentration on Osmosis in Potato Cylinders
Hypothesis: Potato cylinders will gain weight when placed in a hypotonic solution (lower salt concentration than the potato) and lose weight when placed in a hypertonic solution (higher salt concentration than the potato).
Methods: Potato cylinders (~2 cm diameter, 2 cm height) were cut from peeled potatoes and placed in different salt solutions (0%, 0.5%, 1%, 2%, and 4%). The initial weight of each cylinder was recorded. The cylinders were incubated at room temperature for 24 hours. After incubation, the cylinders were removed from the solutions, blotted dry, and weighed again. The percentage change in weight was calculated for each cylinder.
Results: The potato cylinders gained weight when placed in the 0% (hypotonic) and 0.5% salt solutions, and lost weight when placed in the 1%, 2%, and 4% (hypertonic) salt solutions. The percentage change in weight was greatest in the 0% and 4% salt solutions.
Conclusion: The results support the hypothesis that potato cylinders will gain weight when placed in a hypotonic solution and lose weight when placed in a hypertonic solution. This is because water moves from areas of low salt concentration to areas of high salt concentration, in order to equalize the salt concentration on both sides of the potato cylinder membrane.
