Which method is most suitable for dissolving more gas in a liquid?
Answer and explanation
Correct answer: Increase pressure and decrease temperature
For most gases, Henry's law shows that higher partial pressure increases the amount dissolved at constant temperature. Gas dissolution is also generally favoured by lower temperature because warming helps gas molecules escape from the liquid. Therefore increasing pressure and cooling are the suitable choices. Opening the vessel lowers gas pressure, while colour has no molecular role in equilibrium solubility.
