Ks: Stability constant of hydrogen sulfate (mol/kg)
Description
Stability constant of hydrogen sulfate (mol/kg)
Usage
Ks(S = 35, T = 25, P = 0)
Arguments
S
Salinity, default is 35
T
Temperature in degrees Celsius, default is 25oC
P
Hydrostatic pressure in bar (surface = 0), default is 0
Value
KsStability constant of hydrogen sulfate (mol/kg), pHscale = free scale
encoding

Details
Note that the arguments can be given as a unique number or as vectors. If the lengths of the vectors are different, the longer vector is retained and only the first value of the other vectors is used. It can therefore be critical to use vectors of the same length.
The pressure correction was applied on the free scale. The pressure correction was applied as described by Millero (1995), and the value was transformed back to the required scale (T, F or SWS).
