CHEAQS has a large
database. 52 cations, 32 ligands, 1763 complexes, 273 solids,
81 adsorption equilibria, 16 redox equilibria, 4 gases, three
models for organic complexation.
But perhaps you want to add something to the database or want to change constants. No problem for CHEAQS Pro. Just fill in forms like the one shown here and click OK.
The database is also well documented. There is a document
available with the selection rules and for each equilibrium
the literature reference, including all conversions or
assumptions. You can download it here
(pdf-document).
(To
read pdf-files, you need a pdf-reader like Foxit Reader
(fast and small)
or Acrobat
Reader.)![]()
