 ammonium, G. 



Derivation, — A mixture of ammonium chloride or 

 sulphate, and calcium carbonate, is sublimed and resub- 

 limed. Ammonium carbonate, so-called, is a mixture of 

 ammonium carbonate and bicarbonate. 



4 NH, 01 + 2 Ca C03 = NH, HCO, .NH.NH, CO, + 2 

 CaCl, + NH3 -h HA 



Properties. — White, hard, translucent, striated masses, 

 having a strongly ammoniacal odor without empyreuma, 

 and a sharp saline taste. On exposure to the air the salt 

 loses both ammonia and carbonic dioxide, becoming opaque, 

 and is finally converted into friable, porous lumps, or a 

 white powder. Soluble in about 5 parts of water. Alcohol 

 only dissolves the carbonate (NH^ NHj CO2).

The aromatic spirit of ammonia nearly resembles ammo- 

 nium carbonate in action, but the alcohol and volatile oils 

 add to the stimulant qualities of ammonia and ammonium 

 carbonate. 



Action Internal. — Ammonium carbonate is decomposed
