what are the rules used to determine the solubility of salt?

  • Chemistry - , Monday, April 23, 2012 at 4:30pm

    Solubility Rules:
    1. Salts of group 1 and ammonia are soluble.
    2. Acetates and nitrates are soluble.
    3. Binary compounds of group 17, except F, are soluble with metals,
    except Ag, Hg+, and Pb.
    4. All sulfates are soluble, except those of Ba, Sr, Pb, Ca, Ag, and Hg+ .
    5. Except for those in rule 1, carbonates, hydroxides, oxides, sulfides,
    and phosphates are insoluble.

    how do you determine the solubility of the following salts:
    1. AgNO3

    2. Ag2SO4

    3. HgCl2

    4. BaSO4

    5. CaCl2

    6. NH4OH

    7. PbCl4

    8. Mg(C2H3O2)2

    9. HgCl

    10. CaF2

    11. CuO

    12. AgI

    13. Al(OH)3

    14. Fe2(CO3)3

    15. CrPO4

    16. K2S
