  • Ammonium (NH4+) dissolve

  • Nitrate (NO3-) dissolve

  • Acetate (C2H3O2) dissolve

Compounds containing the following MAY dissolve (with exceptions noted)

  • Cl-, Br-, or I-

    •  if the above contain Ag+, Pb+2, or Hg+2, it will not dissolve

  • Sulfate (SO4-2)

    • The following sulfate compounds do not dissolve:

      • AgSO4

      • PbSO4

      • HgSO4

      • CaSO4

      • SrSO4

      • BaSO4

Compounds containing the following generally DO NOT dissolve (unless exception noted)

  • Chromate CrO4-

    • unless contains group 1 metal or ammonium (normal solubility rules apply)

  • Phosphate (PO4-3)

    • unless contains group 1 metal or ammonium (normal solubility rules apply)

  • Carbonate (CO3-2)

    • unless contains group 1 metal or ammonium (normal solubility rules apply)

  • Hydroxide (OH-)

    • unless contains group 1 metal or Ba+2, Sr+2, Ca+2
