WebApr 8, 2024 · Henry’s law was given by an English chemist named William Henry in the early 19 t h century. Henry’s law states that at a constant temperature, the amount of gas particles dissolved in the liquid solution is directly proportional to the gas partial pressure which is above the liquid. The mathematical formula of Henry’s law is shown below.
