For what anions are most of the compounds usually insoluble?

Model I: Rules of Solubility in Aqueous Solutions
Several solid compounds are placed in water to determine if they are soluble. The
results are shown in the chart below. An X indicates that the compound does not
dissolve in water. If it does dissolve no mark is made.
The top row shows the cation in the compound. The far left column shows the anion
in the compound. For example: Mg(OH)2 is insoluble, MgBr2 is soluble, AgCl is
insoluble.
Table 1- This table presents an overview of solubility of selected salts in water.
