Definition
Umbrella term for all variants of Henry’s law constants that are defined in such a way that the numerical value increases with increasing volatility of the solute. Variants include \(H_{\rm{v}}^{pc}\), \(H_{\rm{v}}^{px}\), \(H_{\rm{v}}^{pw}\), and \(H_{\rm{v}}^{cc}\), as discussed elsewhere in this section.
