Umbrella term for all variants of Henry’s law constants that are defined in such a way that the numerical value increases with increasing solubility of the solute. Variants include $H_{\mathrm{s}}^{cp}$, $H_{\mathrm{s}}^{xp}$, $H_{\mathrm{s}}^{bp}$, and $H_{\mathrm{s}}^{cc}$, as discussed elsewhere in this section.
