Osmosis and reverse osmosis
Water flows through a membrane into a solution until the liquid height pushes back. Apply pressure to reverse it.
Open the interactive simulation →How to use this simulation
- Choose a solute and set its concentration and the temperature.
- Press play and watch the level difference grow.
- Raise “Pressure applied to the solution” above π to reverse the flow.
What to notice
- Osmotic pressure π = iCRT.
- Pressure above π pushes water out of the solution — reverse osmosis.
