Only a few supplies are required for this experiment. Gather a large potato, knife, two plastic plates, salt and water.
The potato that was in plain water will not look much different than before, except it may be a bit more rigid. That is because the plain water moved into the potato's cells. The potato in the salt water will be slightly discolored, soft and flexible. This is because the contents of the potato's cells moved out of the potato and into the salt water by osmosis.Learn more about Chem Lab
