Henry's lawMediumQuestion 750010

Question

Henry's law states that the solubility of a gas in a liquid is:
  1. A
    Proportional to its partial pressure above the solution
    Correct
  2. B
    Independent of pressure
  3. C
    Proportional to temperature
  4. D
    Inversely proportional to molar mass

Correct answer

Proportional to its partial pressure above the solution

Explanation

Henry's law: p = KH × x (or C = KH' × p). The concentration of a dissolved gas is proportional to its partial pressure. Used to explain carbonation, oxygen solubility in blood.
