If the partial pressure of oxygen above water is increased, what happens to oxygen solubility in water?
Answer and explanation
Correct answer: Solubility will increase
At constant temperature, Henry's law states that the amount or mole fraction of a gas dissolved in a liquid increases with the gas's partial pressure. Therefore, raising oxygen's partial pressure above water increases the equilibrium concentration of dissolved oxygen, within the range where the law applies. The total pressure need not be confused with oxygen's individual partial pressure.
