Solubility rules
Salts are prepared by different methods, depending on whether the salt is soluble or insoluble so it is important to know the solubility of salts
Solubility of the common salts
Salts | Soluble | Insoluble |
|---|---|---|
Sodium, potassium and ammonium | All | None |
Nitrates | All | None |
Chlorides | Most are soluble | Silver and lead(II) |
Sulfates | Most are soluble | Barium, calcium and lead(II) |
Carbonates | Carbonates of sodium, potassium and ammonium | Most are insoluble |
Hydroxides | Hydroxides of sodium potassium and ammonium (calcium hydroxide is sparingly soluble) | Most are insoluble |
