General Solubility Rules 1. All nitrate (NO 3 - ), chlorate (ClO 3 - ) and acetate (C 2 H 3 O 2 - ) salts are soluble. 2. All ammonium ion (NH 4 + ) salts and all Group 1 metal salts ( Li + , Na + . K + , Cs + and Rb + ) are soluble (with only 4 known exceptions which we will not use in C111). 3. Salts containing halide ions (Cl - , Br - - , and I - ) are soluble except Ag + , Pb 2+ , and Hg 2 2+ salts. 4. F - salts are soluble except those of group II metals (Mg 2+ , Ca 2+ , …) and Pb 2+ . 5. Most sulfate salts are soluble. Exceptions are BaSO 4 , PbSO 4 , Hg 2 SO 4 and CaSO 4 . 6. Oxide, O 2 - , and hydroxide, OH - , salts are “insoluble” except for ammonium and

Most sulfide (S 2-), sulfite (SO 3 2-), carbonate (CO 3 2-), chromate (CrO 4 2-), phosphate (PO 4 3-), arsenate (AsO 4 3-), oxalate (C 2 O 4 2-) and borates (BO 3 3-) are insoluble. Exceptions are ammonium ion and Group 1 metal salts of these ions, which are all soluble. (See rule 2, above)....
