Henry’s law solubility constant (via c and p)

defined via amount concentration and partial pressure
symbol: Hscp, units: molm−3Pa−1, molL−1bar−1
synonym: Henry solubility (defined via amount concentration and partial pressure)
https://doi.org/10.1351/goldbook.09024
Amount concentration cl of a species in the liquid phase divided by the partial pressure p of that species in the gas phase under equilibrium conditions at infinite dilution: Hscp:=limcl→0clp
Note:
The coherent SI unit for Hscp is molm−3Pa−1. Another commonly used unit is molL−1bar−1, equivalent to 10×10−2 molm−3Pa−1.
Example:
The Henry solubility of ozone in water at T=298.15 K is Hscp(OA3)=1.0×10−4 molm−3Pa−1.
