olm.calcite.H2CO3sfromPCO2

olm.calcite.H2CO3sfromPCO2(PCO2, T_K=298.15, T_C=None)

Calculate concentration of carbonic acid + aqueous CO2 in equilibrium with a certain PCO2. [H2CO3s] = [H2CO3] + [CO2]

Parameters:

PCO2 : float

partial pressure of CO2

T_K : float, optional temperature in degrees Kelvin (default = 273.15 + 25)

T_C : float, optional

temperature in degrees Celsius (default = None). If None, function assumes T_K was given or uses default value. If T_C is given in function call, then function uses T_C value to calculate T_K.

Returns:

H2CO3s : float

concentration of carbonic acid + aqueous CO2 in mol/L
