A compound containing an anion from group 17 (halides) is likely soluble. Exceptions: Ag+, Hg22+, and Pb2+ halides are insoluble. A compound containing nitrate (NO3-) or acetate (CH3CO2-) is likely soluble. A compound containing sulfate (SO42-) is likely soluble. Exceptions: Ba2+, Hg22+, and Pb2+ are insoluble. Any other ionic compounds are likely insoluble. 04_03_Table.jpg
