Solubility Rules Flashcards
All Group I compounds are…
soluble regardless of the negative counter ion! (Li, Na, K, etc.)
Ammonium compounds are…
always soluble, since NH4+ can replace Group I ions.
All nitrate (NO3)- compounds are…
soluble regardless of the positive counter ion!
Almost all chloride compounds (and many bromides and iodides) are…
soluble. Common exceptions include AgCl, Hg2Cl2, PbCl2.
Most hydroxide compounds are..
NOT soluble. Common exceptions: LiOH, NaOH, KOH, RbOH, CsOH; Ca(OH)2, Sr(OH)2, Ba(OH)2.
Metal sulfides are generally…
insoluble, except for Group I compounds.
Most carbonates are…
insoluble (except Group I compounds). CaCO3 is found in egg shells, marble, limestone, and the lime water test.
Many sulfates are…
insoluble (except you know what). BaSO4 is used for gastrointestinal tract imaging.
Copper (II) phosphate forms…
a flocculent, blue precipitate.
