What happens when you put a slice of potato in distilled water?
The first potato slice is placed in distilled water, which is a high concentration of almost pure water, definitely higher than that which the potato’s cells contain. This solution is referred to as hypotonic. The water will diffuse into the cells of the potato, causing them to swell; the cells may be characterized as being “turgid”, or swollen.
Why do potatoes shrink in a 0 grams solution?
The shrinking and expanding of the potato strips is due to osmosis. Potatoes are made of cells, and their cell walls act as semipermeable membranes. The 0 grams solution contains less salts and more water than the potato cells (which have more salts and less water).
Why are potato strips easier to bend with salt?
Due to the shrinking of the potato cells the potato strip also becomes less rigid. If you bent the potato strips, you should have noticed that those that had been in the solution with the highest amount of salt were much easier to bend than the potato strips in the water without salt.
What happens when you put salt on a potato?
If the salt concentration in the cup is higher than inside the potato cells, water moves out of the potato into the cup. This leads to shrinkage of the potato cells, which explains why the potato strips get smaller in length and diameter. Due to the shrinking of the potato cells the potato strip also becomes less rigid.
The first potato slice is placed in distilled water, which is a high concentration of almost pure water, definitely higher than that which the potato’s cells contain.

Why are potatoes full of water and starch?
Osmosis, the process in which solvent molecules move from an area of lower solute concentration to an area of higher solute concentration, can easily be demonstrated with potato experiments. Potatoes are full of both water and starch, and will gain water when immersed in watery solutions.
What happens to slices of potato in osmosis?
Educators go through a rigorous application process, and every answer they submit is reviewed by our in-house editorial team. The process that happens to both potato slices is called osmosis, which is a diffusion of water across the semipermeable membrane the potato slice cells possess.
Why are potatoes more flexible in Salt than sugar?
Observe that the slice placed in salt is very flexible, while the slice placed in sugar is flexible, but less so. Since potatoes already contain sugar, less water will diffuse out of the potato placed in sugar water. The slice placed in water will be rigid, since it will absorb water.
