14 Solubility Rules 1. All nitrates, acetates, and chlorates are soluble. 2. All chlorides, bromides, and iodides are soluble except for Ag+, Hg22+, and Pb 2+3. All sulfates are soluble except for Ca 2+, Sr 2+, Hg22+, Pb2+, and Ag+4. All carbonates, chromates, sulfites, and phosphates are insoluble except those of group I and NH4+5. All hydroxides are insoluble except for those of group I and lower II6. All sulfides except those of the I and II groups are insoluble7. Salts containing a group I metal or the ammonium ion are soluble
