Solubility Rules for some ionic compounds in water Soluble Ionic Compounds 1. All sodium (Na + ), potassium (K + ), and ammonium (NH 4 + ) salts are SOLUBLE. 2. All nitrate (NO 3 - ), acetate (CH 3 CO 2 - ), chlorate (ClO 3 - ), and perchlorate (ClO 4 - ) salts are SOLUBLE. 3. All chloride (Cl - ), bromide (Br - ), and iodide (I - ) salts are SOLUBLE -- EXCEPT those also containing: lead, silver, or mercury (I) (Pb 2+ ,Ag + , Hg 2 2+ ) which are NOT soluble. 4. All sulfate (SO 4 2- ) salts are SOLUBLE - - EXCEPT those also containing: calcium, silver, mercury (I), strontium, barium, or lead (Ca 2+ , Ag + , Hg 2 2+ , Sr 2+ , Ba 2+ , Pb 2+ ) which are NOT soluble. Not Soluble Ionic Compounds 5. Hydroxide (OH - ) and oxide (O 2- ) compounds are NOT SOLUBLE -- EXCEPT those also containing: sodium, potassium, or barium (Na

Sulfide (S 2-) salts are NOT SOLUBLE -- EXCEPT those also containing: sodium, potassium, ammonium, or barium (Na + , K + , NH 4 + , Ba 2+ ) which are soluble. 7. Carbonate (CO 3 2-) and phosphate (PO 4 3-) salts are NOT SOLUBLE -- EXCEPT those also containing: sodium, potassium, or ammonium (Na + , K + , NH 4 + ) which are soluble. Soluble compounds are defined as those that dissolve to the extent of 1 g or more per 100 g water. NOT soluble compounds are further classified as: -Slightly soluble, which dissolve to the extent of 0.01 g to 1 g per 100 g water. -Difficultly soluble or Insoluble, for which less than 0.01 g per 100 g water will dissolve....
