Description

PUBLIC function: calculates the dissociation constant of NH4

Usage

1
K_NH4(S, t, p=0, SumH2SO4=NULL, SumHF=NULL, khf="dickson", khso4="dickson")

Arguments

S

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

t

temperature in degrees centigrade

p

gauge pressure (total pressure minus atmospheric pressure) in bars

SumH2SO4

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

SumHF

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

khf

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

khso4

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

Value

the dissociation constant of NH4 in mol/kg-solution on the free proton pH scale
