SOLUBILITY RULES
Solubilities of ionic substances in water:
1)
All salts of Na*, K*, NH4+ are soluble in water.
2) All salts of NO3, CH3CO0- (C2H3O2) are soluble in water.
3) All salts of CI, Br, I are soluble in water (except Ag*, Pb2-, Hg2?+)
4) All salts of So,2- are soluble in water ( except Ba2-, Pb2-, Sr2+)
So.2- of Ca2+, Ag*, Hgz2- are slightly soluble in water.
5) All salts of CO;2, PO- are insoluble in water (except Na*, K*, NH4*)
6) All salts of S2- are insoluble in water ( except Na*, K*, NH, Ba2+ Ca2+, Mg2+, Sr2-)
7) All salts of 02-, OH- are insoluble in water ( except Na*, K*, NHa, (Ba2-))
OH- of Ca2+, Sr2+ (Ba2+) are slightly soluble in water
OH of Mg2* is very very slightly soluble in water
