Info on log Q/K for Mineral saturation Spec8?

Recommended Posts

I understand what the log( Q/K) means, but I am wondering if anyone has any information on how the program is calculating the values for k and q. I've been looking in the various manuals but have yet to find anything about how it actually does it. Thanks

Hello,

Log K values are derived from the thermo dataset used in the calculation. To see which dataset is currently loaded for your calculation in each app, go to File – File Properties – Thermo data. The Q values for a reaction, however, depend on the activities of species involved in that reaction which are dependent on the thermodynamic data for all other dissolved species in the solution matrix. To overall, Q is a quantity that changes as the reaction approaches equilibrium (K).

Hope this helps.
