Rule 1: Nitrates and acetates are generally soluble
|
Exception: No common ones. Silvers acetate. mercurous
acetate and actetate are moderately soluble |
|
|
Rule 2: Compounds of the alkali metals and the
ammonium ion are generally soluble |
Exception: No common ones
|
|
|
Rule 3: Chlorides, bromides, and iodides are
generally soluble |
Exception: The halides of Ag1+, Hg2
2+, Pb2+; also HgI2, BiOCl and SbOCl |
|
|
Rule 4: Sulfates are generally soluble
|
Exception: PbSO4, SrSO4 and BaSO4 are insoluble.
CaSO4, Hg2SO4, and AgSO4 are moderately soluble. The corresponding bisulfates are more soluble. |
|
|
Rule 5: Carbonates, chromates, phosphates, and
sulfites are generally insoluble |
Exception: Those of the alkali metals and ammonium are
soluble. Many acid phosphates are soluble. i.e. Mg(H2PO4)2 and Ca(H2PO4)2 |
|
|
Rule 6: Sulfides are generally insoluble
|
Exception: Those of alkali metals and ammonium are
soluble. The alkaline earth metals are soluble. Cr2S3 and Al2S3 decompose and precipitate as hydroxides. |
|
|
Rule 7: Hydroxides are generally insoluble.
|
Exception: Those of alkali metals and ammonium are
soluble. The hydroxides of Ba, Sr, and Ca are moderately soluble. i.e. Ca(OH)s |
|
|
Rule 8: Almost all ionic compounds containing
NO2-, ClO4-, ClO3-, ClO2-, ClO- are soluble. |
None

Common strong acids (strong electrolytes) are
HCl, HBr, HI, HNO3, H2SO4, HClO3, and HClO4 |
|
|
Most bases are weak electrolytes
|
Strong basic hydroxides (strong electrolytes)
are those of Li, Na, K, Rb, Ca, Sr, and Ba. |
|
|
Most salts are strong electrolytes
|
Important weakly ionize salts are HgCl2,
Hg(CN)2, CdCl2, CdBr2, CdI2, and Pb(CH3COO)2. |
