calc_K: Calculate a single equilibrium constant

Description

Calculate a single specified stoichiometric equilibrium constant at given temperature, salinity, pressure and the concentration of magnesium, calcium, sulphate, and fluorine.

Usage

calc_K(
  k,
  temp_c = 25,
  sal = 35,
  p_bar = NULL,
  magnesium = 0.0528171,
  calcium = 0.0102821,
  sulphate = NULL,
  fluorine = NULL,
  method = "r_polynomial"
)
calc_Ks(
  ks = NULL,
  temp_c = 25,
  sal = 35,
  p_bar = NULL,
  magnesium = 0.0528171,
  calcium = 0.0102821,
  sulphate = NULL,
  fluorine = NULL,
  method = "r_polynomial"
)
calc_all_Ks(
  temp_c = 25,
  sal = 35,
  p_bar = NULL,
  magnesium = 0.0528171,
  calcium = 0.0102821,
  sulphate = NULL,
  fluorine = NULL,
  method = "r_polynomial"
)

Value

A single K at given conditions

Data.table of multiple Ks at given conditions

Data.table of all Ks at given conditions

Arguments

k: K to be calculated
temp_c: Temperature (Celcius)
sal: Salinity
p_bar: Pressure (Bar) (optional)
magnesium: magnesium concentration in mol/kgsw. If None, modern is assumed (0.0528171). Should be the average magnesium concentration in seawater - a salinity correction is then applied to calculate the magnesium concentration in the sample.
calcium: calcium concentration in mol/kgsw. If None, modern is assumed (0.0102821). Should be the average calcium concentration in seawater - a salinity correction is then applied to calculate the magnesium concentration in the sample.
sulphate: Sulphate concentration in mol/kgsw. Calculated from salinity if not given.
fluorine: Fluorine concentration in mol/kgsw. Calculated from salinity if not given.
method: string describing method which should be either 'myami', 'myami_polynomial', or 'r_polynomial' (Default: 'r_polynomial').
ks: character vectors of Ks to be calculated e.g., c("K0", "K1") (Default: NULL, calculate all Ks)

Functions

calc_Ks(): Wrapper to calculate multiple stoichiometric equilibrium constants at given temperature, salinity, pressure and the concentration of magnesium, calcium, sulphate, and fluorine.
calc_all_Ks(): Wrapper to calculate all stoichiometric equilibrium constants at given temperature, salinity, pressure and the concentration of magnesium, calcium, sulphate, and fluorine.
