Osmosis and Diffusion

I do one with Elodea leaves and saturated salt solutions that works pretty well. The fresh-water aquatic cells are very permeable to water but not so much to the ions, so the cells shrink from osmotic loss. It's simple, easy to set up and for the students to see, and I can even kind ...

Re: Hypotonic/Isotonic Solution Question?

Osmosis is the diffusion of water through a semi-permeable membrane, from a low concentrate solution (high water potential) to a highly concentrated solution (low water potential), up a solute concentration gradient. [...] Net movement of solvent ...
