R: K_BOH3

K_BOH3

R Documentation

K_BOH3

Description

PUBLIC function: calculates the dissociation constant of B(OH)3

Usage

K_BOH3(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 B(OH)3 in mol/kg-solution on the free proton pH scale
