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
You follow the rules Kelly gave you.
