kconv: Conversion factors to change the pH scale of dissociation constants

Description

Conversion factors from the total scale to the free and seawater scales

Usage

kconv(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

• The function returns a list with 3 conversion factors :
• ktotal2SWS
  to convert from the total scale to seawater scale
• ktotal2free
  to convert from the total scale to the free scale
• kfree2SWS
  to convert from the free scale to the seawater scale

Examples

##To convert dissociation constants from the total scale to the free scale
## (at salinity=35, temperature=25oC and atmospheric pressure):
kconv(35,25,0)
conv <- kconv()
 c(K1_total=K1(),K1_SWS=K1()*conv$ktotal2SWS,K1_free=K1()*conv$ktotal2free)
