What is the molecular geometry of arsine?
The molecule has a trigonal pyramidal shape, similar to ammonia, but with a smaller bond angle.
What does arsine do to the body?
Arsine causes massive hemolysis and results in anemia, jaundice, and hemoglobinuric renal failure. The intensity and length of arsine exposure, and the premorbid condition of the person exposed, will contribute to the time of onset and the severity of illness.
Is arsine a molecule?

How much arsine is lethal?
Arsine gas is the most toxic form of arsenic. Inhalation of over 10 ppm is lethal and at concentrations higher than 25 ppm are reported to be lethal in less than an hour after exposure., while over 250ppm is reported to be instantaneously lethal.
What does arsine smell like?
Arsine is a colorless, flammable, non-irritating toxic gas with a mild garlic odor.
Is arsine polar or nonpolar?
The Arsenic-hydrogen bonds in the Arsine or Arsenic trihydride molecule(AsH3), for example, are polarised toward the more electronegative value Arsenic atom, and because all (As-H) bonds have the same size and polarity, their sum is non zero due to the AsH3 molecule’s bond dipole moment, and the AsH3 molecule is …
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 does arsine mean?
Definition of arsine : a colorless flammable extremely poisonous gas AsH3 with an odor like garlic also : a derivative of arsine.
What type of bond is arsine?
ionic
The metal appears to be in a +3 oxidation state, and the bonding is predominantly ionic. These hydrides are used as reducing agents in some processes (e.g., metallurgy).
What poison smells like garlic?
What arsine is. Arsine is a colorless, flammable, non-irritating toxic gas with a mild garlic odor. Arsine is formed when arsenic comes in contact with an acid. Arsine is similar to a gas called stibine, which is formed when the metal antimony comes in contact with an acid.
What poison smells like licorice?
4-Methylcyclohexanemethanol (MCHM) is an alicyclic alcohol that commonly exists as a mixture of trans (shown) and cis isomers. It is a colorless liquid that smells like mint or licorice. It is toxic to animals and humans, if it is breathed, swallowed, or allowed to come into contact with skin.
Is arsine gas poisonous?
What arsine is. Arsine is a colorless, flammable, non-irritating toxic gas with a mild garlic odor. Arsine is formed when arsenic comes in contact with an acid.
Is arsenic an insecticide?
Geetu Saxena, in Handbook of Toxicology of Chemical Warfare Agents, 2009 Arsenic is well known as an insecticide in the form of lead arsenate, arsenic acid, etc., and in pharmacy, especially in the form of salvarsan and neosalvarsan.
What is the Order of toxicities of arsenic species?
According to extensive literature survey carried out, the order of toxicities of arsenic species have been found to be: arsenite > arsenate > monomethyl arsenic acid (MMA) > dimethyl arsenic acid (DMA). Consequently efforts are being directed toward combating this problem.
How is arsenic metabolized in fish?
Whereas in humans and most mammals the arsenic metabolism ends with the excretion of the stable pentavalent DMA V, fish and others produce and/or store arsenobetaine, containing four arsenic–carbon bonds, and marine algae among others produce arsenic compounds containing a ribose moiety.
What is the maximum arsenic sorption for as (III) and as (V)?
While the maximum arsenic sorption was found to be 3.69 mg g − 1 for As (III), while for As (V), it was found to be 3.71 mg g − 1. But the only limitation of this method was reduction in arsenic uptake in presence of competing anion phosphate.
