What do the tags on different chemical names and formulas represent in the thermo database?
For example: Fe2(SO4)3(c) and Fe(OH)2(ppd).
I know that generally (s)=solid, (aq)=aqueous, (g)=gas, (am)=amorphous, but there are several like (c) that I can't figure out.
Is there any guide to the different tags?
