K_W {AquaEnv} | R Documentation |
PUBLIC function: calculates the ion product of H2O
K_W(S, t, p=0, SumH2SO4=NULL, SumHF=NULL)
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) |
the ion product of H2O in (mol/kg-solution)2 on the free proton pH scale
