Dear Sir, Could please clarify a concept for me if possible? If I can only find one set of constants for a metal-ligand reaction, and this set of constants is determined at 30 degrees celsius at an ionic strength of 0.5 M. When I construct an input file for PHREEQC to do speciation modeling, if I define the reactions and put in this set of constants, would PHREEQC modify the constants to adapt to zero ionic strength and 25 degrees celsius conditions? Or do I need to convert the constants to suit the zero ionic strength, 25 degrees environment first before I construct the input file? Thanks in advance for your help! Yours Sincerely, Zhi Ling Zeng
