Halides (Chlorides, Bromoides, Iodines)
Yes, except PMS (Lead, Mercury, Silver)
Carbonates (CO3 2-)
No, except paired with Group 1A metals/NH4+
Phosphates (PO4 3-)
No, except paired with Group 1A metals/NH4+
Hydroxides (OH-)
No, except paired with Group 1A metals/NH4+

NAGSAG Rule
Nitrates, Acetates, Group 1 Metals, Sulfates, Ammonium, Group 17 always soluble
PMS
Pb2+ (Lead), Mercury (Hg2 2+), Silver (Ag+) insoluble
CBS
Calcium (Ca2+), Barium (Ba2+), Strontium (Sr2+) makes sulfates insoluble
