Arsenic acid or arsoric acid is the chemical compound with the formula H 3 AsO 4. More descriptively written as AsO(OH) 3 , this colorless acid is the arsenic analogue of phosphoric acid . Arsenate and phosphate salts behave very similarly.
Arsenic forms colorless, odorless, crystalline oxides As 2 O 3 ("white arsenic") and As 2 O 5 which are hygroscopic and readily soluble in water to form acidic solutions. Arsenic(V) acid is a weak acid and the salts are called arsenates, [5] the most common arsenic contamination of groundwater, and a problem that affects
Arsenic(V) acid is a weak acid and its salts, known as arsenates, [36] are a major source of arsenic contamination of groundwater in regions with high levels of naturally-occurring arsenic minerals. [37]
Phosphorous acid exists as the dihydroxy tautomer in contrast to arsenous acid.. As(OH) 3 is a pyramidal molecule consisting of three hydroxyl groups bonded to arsenic. The 1 H NMR spectrum of arsenous acid solutions consists of a single signal consistent with the molecule's high symmetry. [3]
Arsenic poisoning (or arsenicosis) is a medical condition that occurs due to elevated levels of arsenic in the body. [4] ... Dimethylarsinic acid, DMA(V), ...
The arsenate is an ion with the chemical formula AsO 3− 4. [1] Bonding in arsenate consists of a central arsenic atom, with oxidation state +5, double bonded to one oxygen atom and single bonded to a further three oxygen atoms. [2]
Arsenic biochemistry is the set of biochemical processes that can use arsenic or its compounds, ... The monomethylated acid, methanearsonic acid (CH 3 AsO(OH) ...
Arsenic contaminated water typically contains arsenous acid and arsenic acid or their derivatives. Their names as "acids" is a formality; these species are not aggressive acids but are merely the soluble forms of arsenic near neutral pH. These compounds are extracted from the underlying rocks that surround the aquifer.
