- The useful idea
Osmosis (, US also ) is the spontaneous net movement of solvent molecules through a selectively permeable membrane from a region of high water potential (region of lower solute concentration) to a region
- How it works
of low water potential (region of higher solute concentration), in the direction that tends to equalize the solute concentrations on the two sides.
- Why it matters
It may also be used to describe a physical process in which any solvent moves across a selectively permeable membrane (permeable to the solvent, but not the solute) separating two solutions of different
Why this matters
Look for Osmosis the next time you notice this pattern in everyday life.
