Solubilities of Common Salts

General Solubility Guidelines

Compounds of Group 1 elements (Li+, Na+, K+, Rb+, Cs+, and Fr+) or ammonium (NH4+) are soluble.

Nitrates (NO3–), chlorates (ClO3–), perchlorates (ClO4–), and acetates (C2H3O2–) are soluble.

Chlorides (Cl–), bromides (Br–), and iodides (I–) are soluble except for those of Ag+, Pb2+, and Hg22+.

With the exception of rule 1, carbonates (CO32–), chromates (CrO42–), phosphates (PO43–), and sulfites (SO32–) are insoluble.

With the exception of rule 1 and the barium ion (Ba2+), hydroxides (OH–) and sulfides (S2–) are insoluble*.

With the exception of rule 2, silver (Ag+), mercury (Hg22+), and lead (Pb2+) salts are insoluble.

With the exceptions of compounds of calcium (Ca2+), strontium (Sr2+), barium (Ba2+), and the ions listed in rule 6, all sulfates are soluble.

*Calcium and strontium hydroxide are classified as slightly soluble, or even soluble in some textbooks.

**Magnesium sulfide decomposes in water.

Explanation / Answer

AgNO3 (aq) + NaCl (aq) =====> NaNO3 (aq) + AgCl (solid)

3MgCl2 (aq) + 2K3PO4 (aq)  =====> Mg3(PO4)2 (solid) + 6 KCl (aq)
