Diffusion & Osmosis Simulator
See solute and water move across a membrane and find out why water follows the higher concentration.

What you can learn
- Diffusion moves particles from high to low concentration.
- Osmosis is the diffusion of water across a semipermeable membrane toward the side with more solute.
- If the solute can cross the membrane, it diffuses until both sides match, and osmosis fades.
Frequently asked questions
What is the difference between diffusion and osmosis?
Diffusion is any movement of particles from high to low concentration. Osmosis is the special case of water moving across a semipermeable membrane.
Which way does water move in osmosis?
Toward the side with the higher solute concentration, which has the lower water concentration.
