phreeqc-database



Dear David and Tony,

Herewith I would like to ask your attention for a small mistake in the
PHREEQC database (and maybe other databases as well).

The values for the analytic expression for the solubility of vivianite
should read:

+234.205 0.0 -12,242.6 -92.510

instead of

-234.205 0.0 +12,242.6 +92.510

The reason is presumably that Al-Borno & Tomson (GCA(58/24), 5373-5378)
report the analytic expression for pK instead of logK.


Best regards,
Jasper Griffioen
