Insert your data in this form and klick on the "calculate" botton to calculate the equilibrium calculation on basis of the alkalinity conservation approach. The description of this method (Luff, Haeckel and Wallmann) is submitted to Computers & Geosciences. For further details, questions or comments sent an E-Mail to (see below).
If no value for TBOH4 is given (0.0), the total borate concentration will be calculated from the given salinity concentration.
* setup attampts: if the first choice of the concentration in thermodynamic equilibrium for the Newton-Raphson Method is too bad for the solution, a new calculation with new randomly generated guess values will be started.
Calculated thermodynamic "constants" with dependency of given temperature, salinity and pressure:
