Question

Sample water A: pH - 7.8, Na - 19.1, K - .358, Mg - 1.19, Ca - 1.05, Cl - 5.67, HCO3 - 17.8, SO4 - 0, NO3 - .032, F - .089. Units: mM
I am only interested in what the PHREEQC input looks like for part C. I am unfamiliar with the program and keep getting an error.

A. Calculate saturation state of these waters for fluorite without making any corrections for ionic strength and complexes. B. Do the same but correct for ionic strength. C. Do the same with PHREEQC.

Explanation / Answer

We have software PHREEQC v 6.0. Or please consider the example. I hope this works.
