NH4+’s are very soluble.
Cl-’s, Br-’s and I-’s are soluble except when
combined with Ag+, Pb2+, Hg22+.
CO32-’s, PO43-’s, S 2-’s generally insoluble
(except for 1A’s and NH4+)
OH-’s: Ba2+, 1A’s are soluble; others
generally insoluble
**The SO42-’s of Ba2+, Ag+, Ca2+, Sr2+,
Pb2+are insoluble. Others are soluble.
