Information request

Dear Sirs, my name is Giuseppe Bassetto and I am an Italian engineer.
Sometime ago I heard about your software named "PHREEQC". I downloaded the
version 1.5.08 from the site
<http://therion.minpet.inibas.ch/minpet/groups/theriak/theruser.html> .
I would like to ask you if, by this software , I am able to understand what
happen, during coolig, at system composed by 100 gr of water, 100 gr of
CaCl2 (by these wheigts I have the composition of the CaCl2.6H2O roughly)
and 10 gr of NH3, starting coolig at 40°C. In the binary system composed by
H2O and CaCl2 at 30 °C roughly I have the precipitation of CaCl2.6H2O. The
presence of ammonia will allow the precipiation of CaCl2.6H20 at 30°C or
not? If not what will it happen?
Thank you very much for your time.
Best regards
Giuseppe Bassetto
