Solubility Rules:
1. Nitrates and acetates are generally soluble.
2. Compounds of the alkali metals and the ammonium ion are generally soluble.
3. Chlorides, bromides, and iodides are generally soluble. EXCEPT the halides of Ag +, Hg22+, and Pb2+; also
HgI2, BiOCl, and SbOCl.
4. Sulfates are generally soluble, EXCEPT PbSO4, Sr SO4, and BaSO4 are insoluble. CaSO4, Hg2SO4 are
moderately soluble. The corresponding bisulfates are more soluble.
5. Carbonates, chromates, phosphates, and sulfites are generally insoluble. EXCEPT those of the alkali metals
and ammonium ions are soluble. Many acid phosphates are soluble, i.e., Mg(H 2PO4)2 and Ca(H2PO4).
6. Sulfides are generally insoluble. EXCEPT those of the alkali metals and ammonium ion are soluble. The
alkaline earth metals are soluble. Cr2S3 and Al2S3 decompose and precipitate as hydroxides.
7. Hydroxides are generally insoluble. EXCEPT those of the alkali metals and ammonium ion are soluble. The
hydroxides of Ba, Sr, and Ca are moderately soluble. The hydroxide of Mg is only very lightly soluble.
8. Almost all ionic compounds containing NO2-, ClO4-, ClO3-, ClO2-, and ClO- are soluble.
9. All inorganic acids are soluble. Solubility of organic acids are variable.
