Ostwald solubility coefficient

Ost·wald sol·u·bil·i·ty co·ef·fi·cient (Λ),

(ost'valt),
the milliliters of gas dissolved per milliliter of liquid and per atmosphere (760 mm Hg) partial pressure of the gas at any given temperature. This differs from Bunsen solubility coefficient (α) in that the amount of dissolved gas is expressed in terms of its volume at the temperature of the experiment, instead of STPD. Thus, λ = α (1 + 0.00367t), where t = temperature in degrees Celsius.
