Table 8.2 p212

Compounds containing the following ions are generally soluble in water:

 1.  Alkali metal ions and ammonium ions, Li+ , Na+ , K+ ,   NH4+

 2.  Acetate ion, C2H3O2-

 3.  Nitrate ion, NO3-

 4.  Halide ions (X), Cl- , Br- , I- (AgX, Hg2X2 , and   PbX2 are insoluble exceptions)

 5.  Sulfate ion, SO4 2- (SrSO4,   BaSO4 ,   and PbSO4 are insoluble exceptions)

 

Compounds containing the following ions are generally insoluble in water:

 6. Carbonate ion,CO32- (see rule 1 exceptions which are soluble)

 7. Chromate ion CrO42- (see rule 1 exceptions which are soluble)

 8.  Phosphate ion PO43- (see rule 1 exceptions which are soluble)

 9. Sulfide ion, S2- (CaS, SrS, BaS, and rule 1 exceptions are soluble in water)

10. Hydroxide ion, OH- [ Ca(OH)2 , Sr(OH)2 , Ba(OH)2 , and rule 1 exceptions are soluble)
