Table 1 - Solubility rules for ionic compounds in water Soluble Compounds 1. All alkali metal components (Group IA) are soluble. 2. All salts containing NH4+1, NO3-1, ClO4-1, ClO3-1 and C2H3O2-1 (acetate) are soluble. 3. All chlorides, bromides and iodides (Cl-1, Br-1 and I-1 respectively) are soluble except when combined with Ag+1, Pb2+ and Hg22+. 4. All sulfates (SO42-) are soluble except when combined with Pb2+, Ca2+, Sr2+, Hg22+ and Ba2+. Insoluble Compounds 5. All metal hydroxides and all metal oxides are insoluble except those in Group IA and those formed by Ca2+, Sr2+ and Ba2+. When metal oxides dissolve, they react with water to form hydrates. The oxide ion (O2-) does not exist in water. For example: Na2O(s) + H2O → 2 NaOH(aq) 6. All salts containing PO43-, CO32-, SO32-, and S2- are insoluble, except those in Group IA and NH4+1.
