olm.calcite.concHFromCaPCO2Relaxed

olm.calcite.concHFromCaPCO2Relaxed(Ca, PCO2, T_C=25.0)

Calculates concentration of H+ from calcium concentration and PCO2 using relaxed charge balance. Uses equation 2.30a from Dreybrodt (1988).

Parameters:

Cafloat

concentration of calcium in mol/L

PCO2float

partial pressure of CO2 (atm)

T_Cfloat, optional

temperature of solution in degrees Celsius (default = 25 C)

Returns:

concHfloat

concentration of hydrogen ions

Notes

Assumes a H20-CO2-CaCO3 system.
