    ARGENTI NITBAS. Arffen^ti Clilor^Wum*i, Chloride of Silver.grs. 1...2,[ci,m 5...15]. ^%c AgCl=143.1 is formed by adding to a solution of argen- . tic nitras hydrochloric acid as long as a precipitate is formed col- lecting and drying the precipitate. Uses: chronic dysentery; diarrhoea; syphilis; epilepsy. Argen^ti Cyan^iduini, Cyanide of Silver. a„pn— Svn; cyanure d'argent, Fr.; cyansilber, G. X»esc.- AgOJN — 133.7 is prepared by passing hydrocyanic gas into a solution ot silver nitrate or by mixing solutions of silver nitrate and potas- sium cyanide, the precipitate being collected and cai-efu y washed. Is a white powder, permanent in dry air, but gradually turning brown by exposure to light, odorless and tasteless, and insoluble in water or alcohol. Uses: this salt is used to form dilute hydrocyanic acid as follows: Silver cyanide parts 6 acid hydrochloric parts 5, aqua destill. 55 parts. Mix the acid and water in a glass-stoppered bottle, add the cyanide._ shake them, and when the precipitate subsides pour off the clear liquid. Argen^ti Io(ri(liiin i, Iodide of Silver, grs. 1...2, [cgrm. 6...12]. I)esc: Agl=234.3 is formed by mixing solutions of potassium iodide, and silver nitrate. The precipitate collected, washed, and dried, should be kept in dark, amber-colored bottles. A heavy, amorphous light-yellow powder, without odor and taste, insoluble in water, alcohol or dilute acids. Action and Uses: yery similar to the nitrate, but not so liable to cause argyria; it is especially recommended for amenorrhoea, syphilis and whooping-cough. Argen'ti Lac'tas* aits. Lactate of Silver, grs. [cgm. 1...12]. Besc: AgC3H503,H20=214.7 is formed by boiling silver car- bonate with lactic acid, collecting and drying the precipitate. Action: similar to the oxide. Argen^ti NFtras atis, Nitrate of Silver, grs. X--^) Syn: argentum nitricum; azotate d'argent, Fr.; silbersalpeter, G. Desc: AgN03=169.7 is prepared by dissolving metallic sil- ver in nitric acid by the aid of heat, evaporating, fusing, and recrystallizing; should be kept in dark amber-colored vials. Crystals are tabular, rhombic, transparent, becoming gray or gray- ish-black on exposure to light, odorless, having a bitter, caustic and strong metallic taste and a neutral Teaction; soluble in 0.8 parts of water and in 26 parts of alcohol; the salt fuses to a faintly- yellow liquid, which, on cooling, congeals to a pearly white, crys- talline mass. Test: an aqueous solution yields, with hydrochloric acid, a white precipitate soluble in ammonia, 1 gvi. of nitrate of silver, when completely precipitated by hydrochloric acid, should yield 0.84 gm. of dry chloride of silver. Synerg: all agents pro- moting waste, as mercury, iodine, antimony, vegetable acids, etc. Antag: soluble chlorides, mineral acids and their salts; alkalies
