A lab experiment for osmosis with potatoes involves putting half a potato in plain water and the other half in salt water and observing the difference in appearance. Osmosis is defined as the manner in which molecules pass through a membrane into a more concentrated solution.Know More
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
