Henry's law,

chemical law stating that the amount of a gas that dissolves in a liquid is proportional to the partial pressure of the gas over the liquid, provided no chemical reaction takes place between the liquid and the gas. It is named after William Henry (1774–1836), the English chemist who first reported the relationship.

Henry’s Law


a proposition according to which at a constant temperature the solubility of a gas in a given liquid (expressed in weight concentration) is directly proportional to the pressure of this gas above the solution. Henry’s law was described by W. Henry in 1803. It holds well only for ideal solutions and is applicable only at low pressures, acquiring the character of a limiting law.
