If the partial pressure of a gas is doubled at constant temperature, what happens to its solubility in a liquid?
Answer and explanation
Correct answer: It will become nearly double
At constant temperature, Henry's law gives a direct proportionality between the dissolved amount or mole fraction of a gas and its partial pressure, within the dilute range where the law applies. Therefore, doubling the partial pressure approximately doubles the dissolved gas concentration. The result is not an inverse or zero change, and it would not remain unchanged under the stated conditions.
