- Arsenious oxide or arsenious anhydride; -- labeled as additionally arsenious acid, white arsenic, and ratsbane.
- regarding, or based on, arsenic; -- said of these compounds of arsenic where this factor has its own highest equivalence; as, arsenic acid.
A metallic factor that forms numerous toxic compounds, arsenic is situated in nature at lower levels mostly in compounds with oxygen, chlorine, and sulfur. They are called inorganic arsenic compounds. Arsenic in plants and pets combines with carbon and hydrogen. This might be called natural arsenic. Organic arsenic is generally less harmful than inorganic arsenic.
metal poisonous to humans that causes cancer of the skin, lung disease, peripheral vascular infection, and liver problems. It's useful for gun-shot and semiconductors.
late 14c., from Old French arsenic, from Latin arsenicum, from late Greek arsenikon "arsenic" (Dioscorides; Aristotle has it as sandarake), modified from Syriac (al) zarniqa "arsenic," from center Persian zarnik "gold-colored" (arsenic trisulphide has actually a lemon-yellow shade), from Old Iranian *zarna- "golden," from PIE root *ghel- (2) "to shine," with derivatives referring to bright products and silver (identify cup). The form of the Greek term is folk etymology, literally "masculine," from arsen "male, powerful, virile" (compare arseno-koites "lying with males" in New Testament) supposedly in reference to the powerful properties of this compound. The mineral (as opposed to the factor) is properly orpiment, from Latin auri pigmentum, so named because it ended up being regularly make fantastic dyes.
Toxic steel (present in atmosphere and water because of industrial contamination) that may cause skin and lung disease, peripheral vascular infection, and liver damage. Arsenic can be used primarily inside manufacture of semiconductors and weapon shots.
Alchemical representation for .
- one of the many symbols utilized in alchemy to designate arsenic.
(n.) Among elements, a solid compound resembling a metal with its actual properties, but in its chemical relations ranking with the nonmetals. It really is of a steel-gray color and brilliant luster, though typically dull from tarnish. It is very brittle, and sublimes at 356 Fahrenheit. It's sometimes found native, but usually combined with silver, cobalt, nickel, iron, antimony, or sulphur. Orpiment and realgar are a couple of of its sulphur compounds, the first which may be the real arsenicum of the ancients. The element and its particular compounds tend to be active poisons. Specific-gravity from 5.7 to 5.9. Atomic fat 75. Image like.

- (a.) related to, or produced by, arsenic; -- said of the substances of arsenic in which this element has its own highest equivalence; because, arsenic acid.
The tri-iodide, AsI3 prepared by subliming arsenic and iodine together in a retort, by leading arsine into an alcoholic iodine solution, or by boiling powdered arsenic and iodine with water, filtering and evaporating, forms brick-red hexagonal tables, of specific gravity 4.39, soluble in alcohol, ether and benzene, and in a large excess of water; in the presence of a small quantity of water, it is decomposed with formation of hydriodic acid and an insoluble basic salt of the composition 4AsOI.
