What is the texture of a potato in salt water?
What is the texture of a potato in salt water?
The one in the regular water looks like a nice white freshly cut piece of potato. Moving on to the flexible test, the regular water one again feels firm and crisp (try to break the piece, it snaps!). The saltwater potato is bendy and doesn’t snap at all. Osmosis is the key to understanding this issue.
What happens to potato strips when placed in salt water?
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.
What is the difference between the potato slice in the salt solution with the potato slice in water?
The potato slice in the salt solution is limp, indicating that more water molecules came out of the potato than went in, because there was a higher concentration of water inside the potato.
What will happen to the potato in the regular water?
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. The water will diffuse into the cells of the potato, causing them to swell; the cells may be characterized as being “turgid”, or swollen.
What happens when you put a potato strip in water?
The strip placed in water increased in length. Water molecules entered the strip because the concentration of the water molecules was less in the cells of the potato than in the pure water. This caused the cells to become turgid (smooth and firm), increasing in size.
Why do potatoes shrink in a salt water solution?
The opposite is the case in the higher concentration salt solutions. 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.
How long does it take to cook potato strips in salt water?
Table 1: Mass of potato strips at 30 minutes intervals in salty water 0f 0.0 molarity Table 2: Mass of potato strips at 30 minutes intervals in salty water 0f 0.12 molarity Table 3: Mass of potato strips at 30 minutes intervals in salty water 0f 0.25 molarity
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.
