Ks: Stability constant of hydrogen sulfate (mol/kg)

In seacarb: Calculates parameters of the seawater carbonate system

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

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.

Value

Ks	Stability constant of hydrogen sulfate (mol/kg), pHscale = free scale
