Henry’s law: gas dissolved in a liquid

Raise the partial pressure of a gas above water and see how much dissolves.

Open the simulation

What to notice

Solubility is proportional to pressure; gases with smaller K_H (like CO₂) dissolve far more. That is why soft drinks are bottled under CO₂ pressure.

Key relation

p = K_H x (x = mole fraction of gas in solution)

Try this

Compare CO₂ and N₂ at 2 bar.

What you can change

• Gas: choose CO₂, O₂, N₂
• Partial pressure: 0.2 to 5 bar

More in Solutions

• Colligative properties: boiling and freezing point
• Osmosis and osmotic pressure
• Raoult’s law: vapour pressure of a mixture
