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 https://wwwbrr.cr.usgs.gov/projects/GWC_coupled/phreeqc <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 V. Calderai, 6 31010 Cimadolmo (TV) Italy
