K_NH4

salinity in practical salinity units (i.e. no unit)

gauge pressure (total pressure minus atmospheric pressure) in bars

total sulfate concentration in mol/kg-solution (calculated from S if not supplied)

SumH2SO4 

total fluoride concentration in mol/kg-solution
    (calculated from S if not supplied)

SumHF 

S, t relation for K\_HF needed for scale conversion: either "dickson" (default, Dickson1979a) or "perez" (Perez1987a)

S, t relation for K\_HSO4 needed for scale conversion: either "dickson" (default, Dickson1990) or "khoo" (Khoo1977)

khso4

PUBLIC function: calculates the dissociation constant of NH4

misc

Toolbox for the experimental aquatic chemist, focused on
acidification and CO2 air-water exchange. It contains all elements to
model the pH, the related CO2 air-water exchange, and
aquatic acid-base chemistry for an arbitrary marine,
estuarine or freshwater system. It contains a suite of tools for
sensitivity analysis, visualisation, modelling of chemical batches,
and can be used to build dynamic models of aquatic systems.
As from version 1.0-4, it also contains functions to calculate
the buffer factors.
