Solubility Rules
Compounds that contain the following Exceptions ions are most SOLUBLE.
Li+1, Na+1, K+1, Rb+1, NH4+1 None
(Hint-these are Group IA ions plus)
NO3-1, C2H3O2
-1 None
Cl-1, Br-1, I-1 (Hint-Group VIIA ions) When combined with Ag+1, Hg+1, Pb+2 compound is not soluble
SO4-2 When combined with Sr+2, Ba+2,
Ca+2, Pb+2 compound not soluble(Hint-mostly Group IIA)
