K_HNO3: dissociation constants of HNO3, HNO2, H2SO4, HS

In AquaEnv: Integrated Development Toolbox for Aquatic Chemical Model Generation

dissociation constants of HNO3, HNO2, H2SO4, HS

Description

PUBLIC function: dissociation constants that are taken invariant

Usage

K_HNO3(...)
K_HNO2(...)
K_H2SO4(...)
K_HS(...)

Arguments

...	not used, included for consistency with other dissociation constantss

Value

the dissociation constant of HNO3, HNO2, H2SO4 and HS in mol/kg-solution on the free proton pH scale.

These dissociation constants are taken as a constant, i.e. they do not vary with temperature nor with salinity.
