In which option will the solubility of a gas in a liquid decrease correctly?
Answer and explanation
Correct answer: On decreasing pressure
At constant temperature, Henry's law gives a direct relation between a gas's partial pressure and its solubility in a liquid. Lowering the pressure reduces the equilibrium amount dissolved, so gas tends to escape. Increasing pressure, cooling, and sealing the vessel generally favour retention of gas instead. The statement refers to the usual behaviour of gases under ordinary conditions.
