Description
The solubility of a gas, SG, is defined as concentration divided by partial pressure, SG = cG·pG-1.
Abbreviation: SG
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). SG 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 SG is related to the activity coefficient (concentration basis) of the gas (see Activity),
γB = SG-1·c°/p°
