Wells's principles and applications of chemistry; . cal importance. 369. Chloride of Nitroge n.—The single compound which chlorin©is known to form with nitrogen, is especially worthy of not© as probably themost dangerous of all chemical combinations. When a bottle of chlorine, perfectly free from greasy matter, is invertedover a leaden dish containing a solution of 1 part of sal-ammoniac (NH4Ci) in12 parts of water—the mouth of the bottle slightly dipping beneath the sur-face—-drops of an oily-looking substance will gradually form upon the liquidand fall to the bottom of the dish,—chlorine slowly disappearing. The fluidsubstance thus generated is chloride of nitrogen. During the whole opera-tion, the bottle must not be approached, unless the face is protected by a wire-gauze mask, and the hands by thick woollen gloves. The leaden dish con-taining the chloride of nitrogen, may, after a time, however, be withdrawn Questions.—HoTT may its properties be illustrated ? WTiat is said of chloride of nitro-gen ? How is it prepared ?. 249 from under the bottle, care being taken to avoid all agitation and contact withthe glass. As thus prepared, it is a volatile, oily liquid, with a peculiar, penetratingodor. When heated to about 200° F., or when merely touched with a greasysubstance, with phosphorus or an alkah, or even when subjected to the slight-est friction or jarring, it explodes with a flash of light and a violence that isdifficult to conceive of. Glass and cast-iron in proximity to it, are shatteredinto fragments, and a single drop has been known to cause a perforationthrough a thick plank. A leaden vessel yields to its effects, and is merelyindented. The chemical constitution of this body is not certainly known; neither arethe principles involved in its remarkable reactions at all understood. Sim-ilar compounds of nitrogen may also be formed with iodine, bromine, and cy-anogen. 370. History of Bleach in g.—The past history and present condi-t
