How does the solubility of a gas in a liquid usually change when pressure increases?
Answer and explanation
Correct answer: Increases
At constant temperature, increasing the pressure of a gas above a liquid generally increases the amount of that gas dissolved in the liquid. More frequent contact between gas particles and the liquid surface favours dissolution, as expressed by Henry’s law. Therefore, higher pressure means higher gas solubility; it does not make the solubility zero or change the liquid’s colour.
