According to Henry's law at constant temperature, the solubility of a gas in a liquid is proportional to what?
Answer and explanation
Correct answer: Partial pressure of the gas
Henry's law is commonly written as p = KH x, where p is the partial pressure of the gas, x is its mole fraction in the liquid, and KH is Henry's constant at that temperature. Rearranging gives x proportional to p when KH is fixed. Therefore higher partial pressure produces higher solubility. Colour, container thickness, and liquid volume alone are not the law's variable.

Partial pressure of the gas
Why is this the correct answer?
Henry's law is commonly written as p = KH x, where p is the partial pressure of the gas, x is its mole fraction in the liquid, and KH is Henry's constant at that temperature. Rearranging gives x proportional to p when KH is fixed. Therefore higher partial pressure produces higher solubility. Colour, container thickness, and liquid volume alone are not the law's variable.
