Corrosive to aluminum; soluble in ammonium hydroxide Arsine 7784-42-1 77.95 Slightly; 28 mL/100 g water (760 mm) at 20 degrees C Colorless, neutral gas; disagreeable garlic odor On exposure to light, moist arsine decomposes quickly depositing shiny black arsenic; human inhalation - TCLo - 3 mL/m 3 , LCLo (30 min) - 25 mL/m 3 , TCLo - 93 uL/m 3 Cadmium 7440-43-9 112.41 Insoluble in water 1 mm Hg at 394 deg C Silver-white blue- tinged lustrous solid; malleable; odorless. Tarnishes in moist air. Becomes brittle at 80 deg C Dichloromethane 75-09-2 84.93 Soluble in about 50 parts water Colorless liquid Vapor is not flammable and when mixed with air is not explosive; LD50 (orally) in rats - 1.6 ml/kg Diborane 19287-45- 7 27.67 Hydrolizes quickly; Hydrolizes in water to H 3 BO 3 . 224 mm Hg at 112 deg C Colorless, flammable gas; repulsive, sickly- sweet odor Reacts with NH 3 to form diborane diammoniate; reacts slowly with Br 2 and explosively with Cl 2 to form boron halides; reacts with hydrocarbons or organoboron compounds to give alkyl- or aryl- boron compounds B-2
