If temperature remains constant and pressure increases, what happens to gas solubility in a liquid?
Answer and explanation
Correct answer: Solubility will increase
This situation is described by Henry’s law. At constant temperature, the solubility of a gas in a liquid is directly related to the partial pressure of that gas above the liquid. Increasing the pressure therefore drives more gas into solution and increases its dissolved amount, within the law’s applicable range. It does not reduce the solubility to zero or remove all gas from the system.
