At constant temperature, how is the solubility of a gas related to the pressure above the liquid?
Answer and explanation
Correct answer: Directly proportional
Henry’s law states that, at constant temperature, the concentration or solubility of a gas dissolved in a liquid is directly proportional to the partial pressure of that gas above the liquid. Thus, if the relevant pressure is doubled under suitable conditions, the dissolved amount tends to double. It is not inversely proportional or independent of pressure.
