) 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.
: It is typically synthesized by treating arsenic trioxide ( As2O3cap A s sub 2 cap O sub 3 arsenic acid
: Chemically, arsenate and phosphate ions behave very similarly, which is a key factor in its biological toxicity. Biological Impact and Toxicity ) with concentrated nitric acid
: 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. Biological Impact and Toxicity : While the acid
Arsenic acid consists of one oxo group and three hydroxy groups attached to a central arsenic atom, a structure more descriptively written as
