Khs: Dissociation constant of hydrogen sulfide (mol/kg)

In seacarb: Calculates parameters of the seawater carbonate system

Description

Dissociation constant of hydrogen sulfide (mol/kg)

Usage

Khs(S=35, T=25, P=0, pHscale="T")

Arguments

S	Salinity, default is 35
T	Temperature in degrees Celsius, default is 25oC
P	Hydrostatic pressure in bar (surface = 0), default is 0
pHscale	choice of pH scale: "T" for using the total scale, "F" for using the free scale and "SWS" for using the seawater scale, default is total scale

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

Khs	Dissociation constant of hydrogen sulfide
