• Soluble Cmps.
• All alkali metal and NH4 cmps.
• All salts of NO3- , ClO4- , ClO3- , and C2H3O2-
• All Cl- , Br - , I- , except when combined with
  Ag, Pb2, Hg22

Solubility Rules (Page 146 of Brady and Holum)

• Insoluble Cmps.
• All OH- and O-2 except alkali metal, NH4 and
  Ca2
• Note, When MO dissolve, they form OH- (aq)
• PO4-3 , CO3-2 , SO3-2 , S-2 are insoluble, except
  for alkali metals and NH4
