The shrinking and expanding of the potato strips is due to osmosis. Potatoes are made of cells and their cells have cell walls that act as semipermeable membranes. The 0 grams saltwater solution is hypotonic compared to the solution inside the potato cells, which means that it contains less salts and more water.

Study of Osmosis by Potato Osmometer
A study of osmosis can be done using a potato osmometer. Osmosis is a phenomenon in which water moves from high solvent to low solvent concentration. The movement of water occurs between two compartments, separated by a semipermeable membrane. The cell membrane of living organisms behaves as a semipermeable or selective membrane.
Potato Osmosis Experiment
1. Mix 40 grams salt into 100ml of water until the salt is fully dissolved. 2. Cut two sticks of potatoes into cubes of 3cm x 3 cm (1.2 in x 1.2 in) 3. Add salt water to one bowl/plate, and regular water to another bowl/plate. 4. Place one stick of potato into the salt water and one stick of potato in the regular water. 5.

Osmosis Lab Conclusion
Since the most hypertonic solution used in lab was 0.8 M, Potato A was placed in 0.8 M solution. The next most mass loss was Potato E, so it was placed in the next most hypertonic solution: 0.6 M. Potato D gained the most mass, meaning it was placed in the most hypotonic solution. Since the most hypotonic solution used in lab was 0.0 M, Potato ...

Conclusion of osmosis potato lab
Osmosis means that water will diffuse from a high concentration of water to a low concentration of water.. Explanation: The concept of osmosis is clearly demonstrated by this experiment.; Water molecules are observed to have moved from the region where they are highly concentrated to the region where they have a low concentration through a semi permeable membrane in the cells of the potato.
