1. Lanthanum is separated as a double salt with ammonium nitrate by crystallization. 2. Sodium sulfate displays a moderate tendency to form double salts . 3. Double salts should not be confused with a complex ion remains unchanged.4. The sulfuric acid method yields the insoluble double salt directly as caesium alum ( ). 5. After, the double salt is dissolved liberating calcium nitrite and regenerating the calcium hydroxide. 6. They form a series of double salts , and include clusters with multiple nickel atoms. 7. These double salts are coloured dark purple. 8. This salt is relatively less soluble than other rare earth double salts and therefore stays in the residue. 9. They are sometimes found in their sodium, potassium, or calcium salts, or even stronger double salts . 10. After separation, the pure precipitated double salt is decomposed, and pure CsCl is precipitated by evaporating the water.
