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.
From the tool guide Ask a follow-upWhich way does water move in osmosis?
Toward the side with the higher solute concentration, which has the lower water concentration.
From the tool guide Ask a follow-upKey ideas
- 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.
Things to try
- Put more solute on the left and watch the water move.
- Make the membrane let solute pass.
- Balance both sides.
- Reset and try the opposite.
Where this is used
Osmosis and diffusion move nutrients into cells, keep plants firm, and are used in kidney dialysis, food preservation and water purification.
How to ask a question people can answer
A good thread on the Diffusion & Osmosis Simulator saves everyone time. Start with a title that names the exact problem, such as the input you used, the result you expected and the result you got. A title like “Not working” is hard to answer, while a title with the specifics gets replies quickly.
- Say what you tried. List the steps you followed and any settings you changed, so replies do not repeat what you already did.
- Share a small example. A short sample input and the output you saw is worth more than a long description. Remove anything private first.
- Mention your setup. Your device, browser and whether you are on a phone or a computer can explain many odd results.
- One question per thread. Separate topics get clearer answers and are easier to find later with the search box above.
- Come back and reply. If a suggestion worked, say so and upvote it, and if you found the fix yourself, post it for the next person.
