Description
The solubility of a gas, S_{G}, is defined as concentration divided by partial pressure, S_{G} = c_{G}·p_{G}^{-1}.
Abbreviation: S_{G}
Reference: Hitchman and Gnaiger 1983
- The solubility of a gas (Hitchman and Gnaiger 1983) — sometimes called the 'solubility coefficient' — is related to the classical Bunsen absorption coefficient, α (see Forstner and Gnaiger 1983). S_{G} has the dimension of molar amount of the gas per volume of the solution per partial pressure of the gas, α has the dimension of volume of the gas (STPD) per volume of the solution per partial pressure of the gas.
- The inverse of S_{G} is related to the activity coefficient (concentration basis) of the gas (see Activity),
γ_{B} = S_{G}^{-1}·c°/p°
