Because water passes out of the raisins [region of higher concentration] into the salt solution [region of lower concentration] through the semipermeable membrane.

∙ 12y agobecause when place in water ,water acts as a hypotonic medium so endosmosis takes place and raisins swell up

What will happen when raisins are placed in concentrated solution of sugar?
when raisins are placed in concentrated solution of sugarthen they will swell up
What happens when you soak raisins in cold water?
it soaks up and turns softer .but does not turn back to a grape it soaks up and turns softer .but does not turn back to a grape
Do raisins kept in distilled water swell up?
Yes, the raisins will swell due to osmosis, where the solvent goes from a low solute concentration to a higher solute concentration, which in this case, is from the distilled water to inside the raisin.
Do wet raisins show endosmosis?
It is an example of hypotonic solution and the raisins will swell up.
Why would a raisin swell when put in hypotonic solution?
Raisin imbibes water and swells up. Imbibition is actually absorption of water as raisins are dry, they take up water from hypotonic solution .
What can happen if a cell placed in pure water 100 percent?
swell up and lyse
Potato cells placed in distilled water will?
take up the water, swell
What will happen if raisin kept in salt solution?
The raisins will swell up due to endososmosis.
What will happen after some time when some dried raisins are placed in hypotonic solution?
There will be no change in the shape of the raisins since the concentration of solvent{most likely water} is equal in the interior and exterior parts of the cell. So no osmosis takes place since the solvent is already in the equilibrium.
How will a raisin sink?
Raisins sink in water because they are denser. However, the carbon dioxide molecules found in soda float to the top because they want to escape from the liquid. These CO2 molecules (seen as bubles) attatch to the raisins pulling them up to the surface as well. When the CO2 bubles reach the surface, they pop and the raisins begin to sink again.
Will raisins rise up and down if placed in soda?
Yes . Hope my answer helps!
Why do dried pulses kept in water swell up after sometime?
Because they absorb the water they're in - which makes them swell up.
