Re: thermodynamic data for hydrohalite




Sorry, I don't have any thermodynamic data for hydrohalite; I checked in
the EQ3/6 database and TEQUIL (an alternative for Pitzer modeling). You
should be able to add a new mineral to PHRQPITZ if you know the
stoichiometry and log K.

Dr. Park et al.,

We are trying to model (using PHRQPITZ) an aqueous spring
system where hydrohalite is a suspected precipitate - is there
thermodynamic data available to add this mineral to the model?

Thanking you,

Wayne
