ARSENIC

n. A$r’se’n-i2k, From dpoevixév, apperixév, orpiment, so called from appevixds, masculine, on account of its strength. Lat., arsenicum, arsenum, arsenium [U. S. Ph.]. Fr., arsenic. Ger., Arsen, Arsenik. It., arsenico. Sp., arsénico. 1. An element frequently ranked among the metals, but now usually regarded as non-metallic. It was known under the form of its.sulphur comunds to the ancients, but was first isolated by the later alchemists (Schroder, 1694; Brandt, 1773). It occurs in nature in combination with iron as lélingite, with iron and sulphur as arsenical pyrites or mispickel, with sulphur as realgar and orpiment, and with nickel, cobalt, and other elements; and it is also found in the free state. A. is procured chiefly by subliming arsenical pyrites, when it is obtained under the form of a steel-gray, brittle, crystalline ma of metallic lustre. On resublimation, this is converted into lustrous rhombohedral crystals, Emanactn with those of tellurium and antimony, of a sp. gr. of 5727, Amorphous a., under the form of either a shining black ma or a grayish powder, and having a sp. gr. of 4710, is obtained by subliming crystalline a, in a current of hydrogen and condensing in the colder portion of the sublimation-tube. On heating, this is converted into crystalline a. A. usually volatilizes directly, without fusion, giving off a lemon colored vapor of garlicky odor, but under increased pre ure can be melted, and then solidifies into a crystalline ma of a sp. gr. of 5709, On exposure to moist air, a. readily oxidizes and becomes covered with a grayish film. In composition a. acts sometimes as a triad, sometimes as a pentad, forming compounds analogous to those of nitrogen, with which it is usually a ociated in systematic chemical treatises. It unites directly with hydrogen, forming arsine, which is the starting-point for the different a. bases (arsines, arsoniums, and their derivatives the arsinic and arsonic acids). 1t also forms compounds with the halogens and with phosphorus: and with oxygen and sulphur it unites to form oxides and sulphides. which in turn give rise to various oxyacids and sulphur acids, and to their salts, the arsenites, met arsenites, arsenates, pyro arsenates, met arsenates, thio arsenites, and thio arsenates, Atomic weight, 749: vapor density, 1498 (the molecule containing 4 atoms of a. instead of 2 as in the case of most elements); symbol, As (occasionally Ar).

Syn.: arsenious acid, white a., white oxide of a., common a, A substance, As,O3, obtained by volatilizing a. in the presence of oxygen. It is commonly prenered by subliming arsenical pyrites, the product of the sublimation being called poison-flour or flowers of a. On resublimation this latter product furnishes amorphous a. trioxide (a. gla , vitreous arsenious acid), a colorle translucent, vitreous ma of sp. gr. of 3°738, soluble in & parts of cold water and 94 of absolute alcohol. This amorphous form on standing is gradually converted into an opaque porcelain-like ma of crystalline structure (opaque or enamel-like arsenious acid), stalline a. trioxide, under the form of octahedral crystals (octahedral arsenious acid) of sp. gr. of 3°689 soluble in 80 parts of cold water and 400 of absolute alcohol, occurs native as arseno lite, and may be obtained artificially by crystallization of either vitreous or opaque arsenious acid from a solution in hydrochloric acid; and, under the form of rhombic crystals (right rhombic arsenious acid), it occurs as claudetite, and is also found among the products of sublimation of arsenical pyrites. A. trioxide is odorle , has a faint sweetish metallic taste, and is volatile, emitting a colorle and odorle vapor. Chemically it is an acid-forming oxide, uniting with water to form true arsenious acid, and also met arsenious acid. It is much used in the preparation of other arsenical compounds, in the manufacture of pigments, and in gla making. In doses Of 1/39-1/a9 grain, it appears to act as a digestive tonic and cardiac and respiratory stimulant, and is much employed as a nerve-tonic in chorea and other nervous affections, as a remedy in chronic skin-disease, and as an adjuvant to or substitute for quinine in the treatment of malarial poisoning, and especially of its non-febrile manifestations. Br the a. eaters of Styria, a. trioxide is used habitually in much larger doses without apparent ill-effects. In ordinary cases in doses of 1 grain or upward it is an acrid poison, producing violent gastro-enteritis with ulceration of the stomach and intestines, and fatt; or parenchymatous degeneration of the liver, heart, and kidneys. The Svan LOU of acute arsenical poisoning are burning pain in the G3 gastrium, marked gastric irritability, vomiting, and purging, the vomited matters, being brownish or bloody and the stools black and fœtid, great thirst, suppre ion of urine, and extreme prostration. If the patient survives this inflammatory stage, nervous symptoms (paresis, convulsions, tetanus, mania, ete.) frequently ensue. This acute form of arsenical poisoning is usually fatal unle the poison is evacuated or rendered inert by combination with some substance which renders it insoluble in the liquids of the stomach, The former is effected by the use of warm water, the sulphates of zinc and copper, and the use of the stomach pump; the latter is ocoertniisteed y the use of the hydrated oxide of iron, magnesia, and sulphureted hydrogen, the first being by far the most efficacious. In addition, demulcents are to be given to reduce the inflammation, stimulants to combat the depre ion, aud narcotics to relieve the pain. Besides this acute form of poisoning by a. trioxide or its salts, a chronic form is observed in those who work with arsenical compounds, or who In other ways take into the system small repeated doses of a soluble a. compound. The symptoms of this chronic arsenical poisoning are gastric disturbance, cutaneous irritation, conjunctival redne and itching, and cedema of the eyelids. In its topical action, a. trioxide is an escharotic and is frequently applied, especially by irregular practitioners, to cancerous and other malignant ulcers. A. trioxide enters into the composition of the liquor pota i i arsenitis, liquor acid i arseniosi, and other official and unofficial solutions and pastes, [B, 3, 5, 159.] —A, trlsul}:allde.

Syn.: arsenious sulphide, yellow sulphide of a., sulph arsenious anhydride. A substance, As,S,, occurring native, under the form of lemon-yellow rhombic prism at i¢ crystals, as the mineral orpiment. and obtainable artificially as an orange-yellow powder by precipitating an acidulated solution of a. trioxide or of an arsenite with hydrogen sulphide. It is ordinarily insoluble in water, but may be obtained in solution by pa ing hydrogen sulphide into a pure aqueous solution of a. trioxide and separating the unaltered a. trioxide by dialysis. This variety of a. trisulphide, called colloidal arsenious su Ë)hide_ forms a yellowish solution with reddish fluorescence, which on evaporation yields a yellowish or reddish, amphorous, translucent substance. Commercial a. trisulphide is prepared by heating together a. trioxide and sulphur, and is really a mixture of the trioxide and trisulphide. It is highly poison ons, while the pure trisulphide is comparatively inert. In composition with basic sulphides, a. trisulphide forms ee salts (thio arsenites), analogous to the arsenites, and is hence often Improperly called aul arsenious acid. A. trisulphide is used as a pigment (king's yellow) in the printing of indigo-colors, and in the manufacture of fire-works; and it has been employed in medicine chiefly as a depilatory, but also formerly by way of fumigation in the treatment of asthma and venereal ulcers.
