Arsenic - Acid

Arsenic acid consists of one oxo group and three hydroxy groups attached to a central arsenic atom, a structure more descriptively written as

: Chemically, arsenate and phosphate ions behave very similarly, which is a key factor in its biological toxicity. Biological Impact and Toxicity arsenic acid

: It is typically synthesized by treating arsenic trioxide ( As2O3cap A s sub 2 cap O sub 3 Arsenic acid consists of one oxo group and

Arsenic acid ( H3AsO4cap H sub 3 cap A s cap O sub 4 ) is a highly toxic inorganic compound that serves as the arsenic analog of phosphoric acid. It is primarily found as a clear, colorless aqueous solution and is one of the most commercially significant pentavalent (oxidation state +5) arsenic compounds. Chemical Identity and Synthesis Chemical Identity and Synthesis Arsenic acid is a

Arsenic acid is a confirmed human carcinogen and a severe environmental pollutant. Its toxicity stems from its ability to disrupt fundamental cellular processes. Arsenic acid (UK PID) - Inchem.org

) with concentrated nitric acid. It can also be produced through the slow hydration of arsenic pentoxide ( As2O5cap A s sub 2 cap O sub 5 ) in water.

: While the acid itself has not been isolated in pure form, its hemihydrate ( ) forms stable white crystals. When heated to , these crystals dehydrate and condense.
