Generalizations
pertaining to the solubilities of inorganic salts may be misleading and if
at all possi-
ble, each specific compound should be checked for its solubility.
The halide, cyanide, and acetate salts of the metals occurring in the center
of the periodic table tend
to be soluble. Alkali and alkaline earth metal salts tend to be insoluble,
as do most of the sulfates,
carbonates, oxides, and hydrated salts. Some of the metal salts form complexes
of varying degree
of stability- -cuprous cyanide forms a very stable complex, mercuric iodide
a very easily decom-
posed complex
.
