What does arsenic and hydrogen make?
Arsine, colourless, extremely poisonous gas composed of arsenic with hydrogen (see arsenic).
What is arsenic hydrogen?
Arsine (AsH3) is a colorless, extremely flammable gas with a garlic-like odor. The most common synonyms for arsine are arsenic hydride, arsenic trihydride, hydrogen arsenide, and arsenous hydride. The relative molecular mass of arsine is 77.95.
What is the chemical formula for arsenic and hydrogen?
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). 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 formula for arsine?

What is the charge of arsenic?
Arsenic (As) anion has -‐3 charge, but also forms cations with +3 or +5 charge.
Is arsenic explosive?
Arsenic is noncombustible, however, Arsenic dust or fine powder can explode when exposed to heat, flame or hot surfaces. Use dry chemical, CO2, water spray or foam as extinguishing agents. POISONOUS GASES ARE PRODUCED IN FIRE, including Arsenic Oxides.
Is arsenic still used today?
Arsenic production has currently ceased in the United States. Arsenic has been phased out of domestic pesticides, but commercial use of imported arsenic is still high [ATSDR 2007].
Is arsenic a poison?
How toxic is arsenic? Arsenic poisoning, or arsenicosis, occurs after the ingestion or inhalation of high levels of arsenic. Arsenic is a type of carcinogen that’s gray, silver, or white in color. Arsenic is extremely poisonous to humans.
What kind of reaction does arsenic have with water?
When heated, arsenic ignites, also forming arsenic (V) oxide. As (III) as arsenate is precipitated by silver ions under neutral and alkaline conditions. As (III) is precipitated by hydrogen sulfide in hydrochloric acid. Arsenic does not react with water in the absence of air, under normal conditions.
Which is the simplest inorganic compound of arsenic?
Arsine ( IUPAC name: arsane) is an inorganic compound with the formula As H 3. This flammable, pyrophoric, and highly toxic pnictogen hydride gas is one of the simplest compounds of arsenic. Despite its lethality, it finds some applications in the semiconductor industry and for the synthesis of organoarsenic compounds.
How are people exposed to high levels of arsenic?
People are exposed to elevated levels of inorganic arsenic through drinking contaminated water, using contaminated water in food preparation and irrigation of food crops, industrial processes, eating contaminated food and smoking tobacco.
What happens when arsenic acid loses a proton?
If arsenic acid, or some other acid for that matter, loses a proton (H +) the remaining part of the molecule has a negative charge. At near-neutral pH, which is common for natural waters, arsenic acid loses one or two H + ions, giving the rest of the molecule a charge of –1 or –2 (H 2AsO 4 – or HAsO 4 2-).
