K_BOH3: 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
