general description |
a grayish metallic solid that turns black upon exposure to air. insoluble in water. toxic by ingestion. |
air & water reactions |
turns black on exposure to air. insoluble in water. |
reactivity profile |
arsenic reacts incandescently with bromine trifluoride, even at 10°c [mellor 2:113 1946-47]. causes bromoazide to explode upon contact. ignites if ground up together with solid potassium permanganate [mellor 12:322 1946-47]. is oxidized by sodium peroxide with incandescence [mellor 2:490-93 1946-47]. a combination of finely divided arsenic with finely divided bromates (also chlorates and iodates) of barium, calcium, magnesium, potassium, sodium, or zinc can explode by heat, percussion, and friction [mellor 2:310 1946-47]. bromine pentafluoride reacts readily in the cold with arsenic. ignition usually occurs. reacts vigorously with fluorine at ordinary temperatures [mellor 9:34 1946-47]. |
health hazard |
poisonous by inhalation of dust or by ingestion. regardless of exposure route, symptoms in most cases are characteristic of severe gastritis or gastroenteritis. all chemical forms of arsenic eventually produce similar toxic effects. symptoms may be delayed. |
