Which statement is correct for solubility of gases?
Answer and explanation
Correct answer: Solubility may increase with pressure
At constant temperature, increasing the partial pressure of a gas generally increases its dissolved concentration in a liquid, as expressed by Henry’s law. Therefore A is correct. Pressure is not irrelevant, gases can dissolve in liquids, and their solubility usually decreases rather than increases when temperature rises, so B, C, and D are incorrect.
