Solubility Rules

A

Rule 1: “always” soluble:
Salts of Li+ group cations and NH4+, Salts of NO3−, C2H3O2−, and ClO4−
Rule 2: “usually” soluble:
Salts of halides, except when paired with Ag+, Cu+, Pb2+ or Hg22+ Salts of SO42−, except when paired with Ca2+, Sr2+, Ba2+, Ag+ or Pb2+
Rule 3: “always” insoluble:
Salts of OH−, CO32−, PO43−, S2−
