Why is the term partial pressure important for gas solubility?
Answer and explanation
Correct answer: Because each gas in a mixture shows solubility according to its partial pressure
In a mixture, the partial pressure of a gas is the pressure that its molecules would exert if they alone occupied the container. Henry's law uses this pressure for that particular gas, not simply the total pressure of the mixture. Therefore, each gas can have a different solubility depending on its own partial pressure. Partial pressure is not a property limited to solids.
