    AMMONII BEOMIDUM. Bromide of Ammonium. NH4Br. May be formed by neutralising hydrobromic acid with ammonia, evaporating and crystallising. In colourless crystals, which may become slightly yellow by exposure to the air. Has a pungent saline taste. May be sublimed unchanged by the application of heat. Readily soluble in water ; less soluble in spirit. Used in whooping cough and epilepsy. Dose^—2 to 20 grains. AMMOKII CARBONAS. Carl)onate of Ammonium. NgHnCoO,,. A volatile and pungent ammoniacal salt, produced by sub- mitting a mixture of sulphate or chloride of ammonium and carbonate of calcium to sublimation and resublimation. It is considered to be a compound of acid carbonate of ammonium (NH4HCO3) with carbamate of ammonium (NH4NH0CO2), and the compound molecule is usually regarded as containing one molecule of each of these salts. In translucent crystalline masses, with a strong ammoniacal odour, and alkaline reaction ; soluble in cold water, more sparingly in spirit. It volatilises entirely w^hen heated, and is readily dissolved by acids with effervescence. 20 grains of Carbonate ) , y \ 26| grains Citric Acid of Ammonium ^ ] ^^^^^^^^^^ \ 28| grains Tartaric Acid Used in preparing Liquor Ammonii Acetafis Fortior and Spiritus Ammonice Aromaticus and Bismuthi Carhonas. Given as a stimulant in chronic bronchitis when expectora- tion is deficient; and as an antacid in dyspepsia. Diose.—3 to 10 grains. AMMOXII CHLOEIDUM. Chloride of Ammonium. NH4CL May be formed by neutralising hydrochloric acid with ammonia or carbonate of ammonium and evaporating to dry- ness. It is usually prepared by sublimation. In colourless inodorous minute crystals, or in translucent fibrous masses, tough, and difficult to powder ; soluble in water and in rectified spirit. Its aqueous solution when heated with caustic potash evolves ammonia, -and when treated with nitrate of silver forms a copious curdy precipitate. When heated it volatilises without decomposition, and leaves no residue. Used in preparing Liquor Hydrargyri Perchloridi and Liquor Ammonice Fortior. Said to be sedative in neuralgia. Used in chronic bron- chitis with profuse expectoration, and as a resolvent of iudura- tions. Dose,—5 to 20 grains.
