Question
On the basis of the general solubility rules, predict the identity of the precipitate that forms when aqueous solutions of
the following substances are mixed.
General Rules for Solubility of Ionic Compounds (Salts) in Water at 25
°C.
1. Most nitrate (NO3) salts are soluble.
2. Most salts of
Na+,
K+, and
+
NH4 are soluble.
3. Most chloride salts are soluble. Notable exceptions are
AgCl,
PbCl2, and
Hg₂ Cl₂.
4. Most sulfate salts are soluble. Notable exceptions are
BaSO4,
PbSO4, and
CaSO4.
5. Most hydroxide compounds are only slightly soluble.* The important
exceptions are
NaOH and
KOH.
Ba(OH)2 and
Ca(OH)2 are only moderately soluble.
6. Most sulfide (
S²-), carbonate (
2-
CO3), and phosphate (
3-
PO4³) salts are only slightly soluble. *
*The terms insoluble and slightly soluble really mean the same thing: such a tiny amount
dissolves that it is not possible to detect it with the naked eye.
