Effective Henry's law constant for species that dissociate in water, accounting for the enhancement due to aqueous dissociation products. The effective constant H* exceeds the intrinsic H because dissolved dissociation products add to the total aqueous loading. Covers diprotic species (CO₂, SO₂) and monoprotic species (HNO₃, K₂=0). From Seinfeld & Pandis Chapter 7, Equations 7.24 (CO₂), 7.41 (SO₂), 7.61 (HNO₃).

Basic Henry's law equilibrium at fixed temperature (Seinfeld & Pandis 2006, Chapter 7, Eq. 7.3). Computes the aqueous-phase concentration C_aq = H_A × p_A, where H_A is the Henry's law constant at the reference temperature and p_A is the gas-phase partial pressure of species A.

Temperature-dependent Henry's law equilibrium for gas–liquid partitioning of soluble atmospheric species. Computes the temperature-corrected Henry's law constant H_T via the van't Hoff equation (Eq. 7.5), the aqueous concentration C_aq via Eq. 7.3, and the liquid-water distribution diagnostics w_L (Eq. 7.1), f_A (Eq. 7.7), and X_aq (Eq. 7.9). From Seinfeld & Pandis (2006), Chapter 7, Section 7.2.
