K_SiOH4
PUBLIC function: calculates the dissociation constant of SiOH4
K_SiOH4(S, t, p=0, SumH2SO4=NULL, SumHF=NULL, khf="dickson", khso4="dickson")
S
: salinity in practical salinity units (i.e. no unit)t
: temperature in degrees centigradep
: gauge pressure (total pressure minus atmospheric pressure) in barsSumH2SO4
: 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)the dissociation constant of SiOH4 in mol/kg-solution on the free proton pH scale
