If you are referring to osmosis, the salt doesn't cross the membrane, water does. Water will move into the salt water to attempt to dilute it to create homeostatsis, or equal concentrations on each side of the membrane.
the water will flow in because the molecules in the pouch cannot flow out and the water particles will be able to flow in because they are smaller than the salt particles.
Well, honey, if that membrane is as tight as my Spanx after Thanksgiving dinner, then ain't no salt particles getting through! So, to answer your question, if the membrane is impermeable, then the concentration of salt particles on either side won't change because nothing can pass through that bad boy. So, sit back and relax knowing that those salt particles are staying put where they belong.
its either the cell membrane, molecules, or plasma
The cell absorbs water through its semipermeable membrane in order to make the ratio of salt particles to water particles equal in the cell and outside the cell. However, the increase in water in the cell makes it explode.
If you think to particles as impurities, non-refinned salt have particles of insoluble impurities.
no, salt is a solute not a solvent, so it will not move across the membrane
Large molecules such as proteins and polysaccharides cannot easily cross a semipermeable membrane due to their size. Additionally, charged molecules like ions may have difficulty crossing depending on the membrane's properties. Lipid-soluble molecules, gases, and small uncharged polar molecules can usually pass through more easily.
Usually not. Try this experiment: Prepare a glass of water and some salt. Add a teasppon of salt into the water. You wouldn't be able to see the dissolved salt particles.
Yes, these particles are microcrystals of NaCl.
Cheese Salt is, are you ready for this?, Salt with cheese in it......
Gases and fluids are all considered fluids which mean they are able to flow. This is because their particles are able to slide into each other. Solids, though some may seem to flow ( salt, sand ) are not able to because their particles are extreamly close together there for they are not able to slide into each other.
I assume you mean semi-permerable membrane that is permeable to the solution (water) but not the solute (salt). Osmosis can only occur if the membrane does NOT allow salt to pass through. Osmosis is the movement of water across a semi-permeable membrane from an area of low salt concentration to higher salt concentration.
