Is arsine heavier than air?
Arsine has not been known to be absorbed into the body through the eyes and the skin. Arsine vapor is heavier than air; so it would be more likely to settle in low-lying areas.
What is the formula of arsine gas?
AsH3
Arsine/Formula
How do you test for arsine?
Laboratory criteria for diagnosis Biologic: No specific test is available for arsine exposure; however, exposure to arsine might be indicated by detection of elevated arsenic levels in urine (>50 µg/L for a spot or >50 µg for a 24-hour urine) and signs of hemolysis (e.g., hemoglobinuria, anemia, or low haptoglobin).
What is the normal boiling point of arsine?
-62.5 °C
Arsine/Boiling point
Which is more stable stibine or arsine?
Although stibine is chemically similar to arsine, it is less stable.
Is arsine a polar molecule?
Answer = AsH3 ( Arsine ) is Polar What is polar and non-polar? SbF5 forms a trigonal bipyramidal shape. Polar. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms.

What does arsine mean?
: a colorless flammable extremely poisonous gas AsH3 with an odor like garlic also : a derivative of arsine.
What is the pH of arsine?
Hydrogen arsenate ( HAsO 4 2 − ) and dihydrogen arsenate ( H 2 AsO 4 2 − ) are the predominant species in an aqueous solution of arsenic acid around pH 7. The terms “arsenite” [arsenate(III)] and “arsenate” [arsenate(V)] are commonly used as names for the species formed from arsenous acid and arsenic acid.

Is Stibine less stable than arsine?
Stibine (SbH3), a toxic gas that is formed when antimony is exposed to nascent hydrogen, equals or surpasses arsine in toxicity and causes a specific toxic action similar to arsine. Stibine is less stable than arsine, so fewer cases of stibine poisoning have been reported.
Is arsine a compound?
Arsine (IUPAC name: arsane) is an inorganic compound with the formula AsH3. This flammable, pyrophoric, and highly toxic pnictogen hydride gas is one of the simplest compounds of arsenic.
What is the vapor density of arsine hydride?
arsenide; AsH3 Chemical Family inorganic, gas, hydrides Product Use industrial Vapor Pressure: 11362 mmHg @ 21.1 °C Vapor Density (air = 1): 2.7
What happens when arsine is heated to 300°C?
Hazards. ARSINE decomposes into its elements (arsenic, gaseous hydrogen) when heated to 300°C. Can form accidentally by the reaction of arsenic impurities with mineral acids (hydrochloric acid, sulfuric acid) in the presence of common metals (iron, zinc). A reducing agent—not oxidized by air at room temperature [Kirk-Othmer, 3rd ed., Vol.
What kind of odor does arsine gas have?
Arsine is a colorless, flammable, and highly toxic gas. It has a garlic-like or fishy odor that can be detected at concentrations of 0.5 ppm and above. Because arsine is nonirritating and produces no immediate symptoms, persons exposed to hazardous levels may be unaware of its presence. Arsine is water soluble.
When do you get exposed to arsine gas?
Exposure frequently occurs when arsine gas is generated while metals or crude ores containing arsenic impurities are treated with acid and this is a common source of exposure. Synonyms include arsenic hydride, arsenic trihydride, arseniuretted hydrogen, arsenious hydride, and hydrogen arsenide.
