Arsenic acid is an arsenic oxoacid comprising one oxo group and three hydroxy groups attached to a central arsenic atom. It has a role as an Escherichia coli metabolite. It is a conjugate acid of an arsenate (1-) and an arsenate ion. Arsenic acid, liquid appears as a clear colorless aqueous solution. Noncombustible Arsenic Acid. Arsenic acid is highly soluble in water: 630g dissolves in 100g water at 20°C. On dehydration it yields arsenic pentoxide, As2O5.

Arsenic acid, H 3 AsO 4, which contains pentavalent arsenic, is a tribasic acid (K 1 = 5.7 × 10 − 3, K 2 = 1.1 × 10 − 7, K 3 = 3.2 × 10 − 12) [26] comparable in strength to phosphoric acid. Hydrogen arsenate (HAsO 4 2 −) and dihydrogen arsenate (H 2 AsO 4 2 −) are the predominant species in an aqueous solution of arsenic acid around pH 7. The terms arsenite [arsenate(III)] and arsenate [arsenate(V)] are commonly used as names for the species formed from arsenous acid. Arsenic(V) acid is a weak acid and the salts are called arsenates, the most common arsenic contamination of groundwater, and a problem that affects many people. Synthetic arsenates include Scheele's Green (cupric hydrogen arsenate, acidic copper arsenate), calcium arsenate , and lead hydrogen arsenate Arsanilic acid, also known as aminophenyl arsenic acid or aminophenyl arsonic acid, is an organoarsenic compound, an amino derivative of phenylarsonic acid whose amine group is in the 4-position Arsenic acid, 75% High Purity Arsenic Acid, Acide Arsenique Sol 75%, Arsenic acid 62

Arsenic acid, liquid. Arsenic acid is the chemical compound with the formula H3AsO4. 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 acid as such has not been isolated, but is only found in solution, where it is largely ionized arsenic acid — noun an acid formed from arsenic pentoxide • Hypernyms: ↑acid Useful english dictionary. arsenic acid — noun A poisonous, white crystalline compound, HAsO, formed from arsenic pentoxide and water; it has the same structure as phosphoric acid, and is used in the manufacture of arsenates Wiktionar Arsenic Acid Chemical Formula. Arsenic pentoxide is the inorganic compound with the formula As2O5. [2] This glassy, white, deliquescent solid is relatively unstable, consistent with the rarity of the As (V) oxidation state. More common, and far more important commercially, is arsenic (III) oxide (As2O3). All arsenic compounds are highly toxic. The reaction to convert soluble arsenic acid to ferric arsenate occurs according to the following reaction: Fe 2 (SO 4) 3 + 2H 3 AsO 4 => 2FeAsO 4 + 3H 2 SO 4. Laboratory precipitation test at a Fe:As ratio of 4, at 33°C and a retention time of 2 hours resulted in arsenic concentrations of 0.2 mg/L at pH 3.5 to 5.0 Arsenic is a trace element that occurs naturally in very small amounts in the diet. Its exact functions are not known. The estimated adult daily intake of arsenic from a typical diet is 12-50 mcg
Arsenic is a natural component of the earth's crust and is widely distributed throughout the environment in the air, water and land. It is highly toxic in its inorganic form. People are exposed to elevated levels of inorganic arsenic through drinking contaminated water, using contaminated water in food preparation and irrigation of food crops. All-trans retinoic acid (ATRA) with chemotherapy is the standard of care for acute promyelocytic leukemia (APL), resulting in cure rates exceeding 80%. Pilot studies of treatment with arsenic. Arsenic also forms numerous organic compounds, as for example tetramethyl diarsine, (CH 3) 2 As―As(CH 3) 2, used in preparing the common desiccant cacodylic acid. Several complex organic compounds of arsenic have been employed in the treatment of certain diseases, such as amebic dysentery, caused by microorganisms Standard Arsenic Solution— Transfer 10.0 mL of Arsenic Trioxide Stock Solution to a 1000-mL volumetric flask, add 10 mL of 2 N sulfuric acid, then add recently boiled and cooled water to volume, and mix. Each mL of Standard Arsenic Solution contains the equivalent of 1 µg of arsenic (As). Keep this solution in an all-glass container, and use. An acid or alkali soil pH also enhances leaching of toxic heavy metals from the soil . Lead, arsenic, and cadmium have also been found in brewed black tea . These soil and air contaminants may be directly related to the use of coal fired power plants. The use of coal in China has increased to 3.8 billion tons or about 47% of global coal.
In many countries in the world, arsenic in the water results in chronic (that is, constant) exposure of people to arsenic. A randomized control trial in Bangladesh found that taking 400 micrograms per day of folic acid for 12 weeks reduced total blood arsenic levels by 13.6% Environmental Context. Arsenic is of significant environmental concern in much of the world because of its contamination of waters, from mining, industry, sewage disposal, and agriculture. The environmental mobility of arsenic is controlled primarily by adsorption onto metal oxides, especially iron. Humic substances (natural organic matter), which are ubiquitous in aquatic and soil. All-trans retinoic acid (ATRA) plus arsenic trioxide was found to be noninferior to ATRA plus chemotherapy, and less toxic, in the treatment of acute promyelocytic leukemia. This is an early exampl..
Molecular formula : CAS : nature : arsenic elements of one or two hydroxy alkyl was replaced by derivatives. Some arsonic acid can be used as a drug or pharmaceutical intermediates, such as the right-aminophenyl ARSACETYL 'Arsenates are salts of arsenic acid, or more formerly orthoarsenic acid.' 'In both cases, an As-mineral (arsenopyrite: FeAsS) in the depth is oxidized to release water-soluble As compounds (arsenious acid, arsenic acid) when the groundwater level is lowered by the active drawing up of water from the well or the detritus carried out from. 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 2 AsO 4 - or HAsO 4 2-) Arsenic is perhaps unique among the heavy metalloids and oxyanion-forming elements (e.g. arsenic, selenium, antimony, molybdenum, vanadium, chromium, uranium, rhenium) in its sensitivity to mobilisation at the pH values typically found in groundwaters (pH 6.5-8.5) and under both oxidising and reducing conditions In the metal complexes, the arsenic acid has a slightly larger binding distance (by 0.07-1.0 Å) and weaker binding energy because the As(V) ion has a slightly larger radius than the P(V) ion, and the electrostatic interaction is the dominating feature in these systems

Arsenic is a toxic trace element, denoted by the symbol As. It is not usually found on its own. Rather, it is bound with other elements in chemical compounds The major metabolic pathway for inorganic arsenic in humans is methylation. Arsenic trioxide is methylated to two major metabolites via a non-enzymatic process to monomethylarsonic acid (MMA), which is further methylated enzymatically to dimethyl arsenic acid (DMA) before excretion in the urine [40, 47] arsenic and arsenic containing compounds were released into the environment in 1997. • Arsenic is found in the preservative chromated copper arsenate (CCA) used to preserve wood. 90% of all arsenic consumed in the U.S. is used in the production of CCA. • Arsenic can be a by-product of mining and smelting, and is of particular concern i Process for separating arsenic acid from an aqueous mixture comp Chemistry of inorganic compounds - Treating mixture to obtain metal containing compound - Group va metal or arsenic Arsenic as a heavy metal and toxic pollutant has been established that has the hepatotoxic effect in animal and human models. Previous studies showed that mitochondria as the first target of arsenic toxicity has a pathogenic role in liver diseases. This study investigated alpha lipoic acid (ALA) as an antioxidant could ameliorate against liver toxicity induced by arsenic in rat mitochondria
Organic forms of arsenic are rare in groundwater, so we will ignore them in this discussion. Most of the arsenic found in groundwater is either inorganic As(III) mainly as uncharged arsenious acid, or inorganic As(V) in the form of arsenic acid minus one or two of its protons (so with a charge of -1 or -2). That's the case at neutral pH Arsenic is a metalloid that occurs in different inorganic and organic - i.e. containing carbon - forms. These are found in the environment both from natural occurrence and from anthropogenic activity. The inorganic forms of arsenic are more toxic as compared to the organic arsenic.
