REVIEW OF SOLUBILITY RULES

  1. All common nitrates, NO3-, are soluble in water.

  2. All common compounds of the Group IA metal (i.e. Na+, K+, etc.) and ammonium ion, NH4+, are soluble in water.

  3. All common halides (Cl-, Br-, I-) are soluble in water except the halide salts of Ag+, Hg22+, and Pb2+.

  4. All common sulfates, SO42-, are soluble in water except PbSO4, Hg2SO4, and BaSO4. Slightly soluble sulfates include CaSO4, Ag2SO4, and SrSO4.

  5. The important soluble metal hydroxides are NaOH and KOH. Most other metal hydroxides are insoluble. Slightly soluble metal hydroxides include Ca(OH)2, Ba(OH)2, and Sr(OH)2,.

  6. All common carbonates, CO32-, phosphates, PO43-, and sulfides, S2- are insoluble in water except those salts of the Group IA metals and NH4+. (The sulfide salts of Group IIA metals are also soluble).
