Sodium arsenate is the inorganic compound with the formula Na 3 AsO 4. Related salts are also called sodium arsenate, including Na 2 HAsO 4 (disodium hydrogen arsenate) and NaH 2 AsO 4 (sodium dihydrogen arsenate). The trisodium salt is a white or colourless solid that is highly toxic. It is usually handled as the dodecahydrate Na 3 AsO 4. 12H ...
The other sodium arsenates are NaH 2 AsO 4 and Na 3 AsO 4, the latter being called sodium arsenate. Disodium hydrogen arsenate is highly toxic. The salt is the conjugate base of arsenic acid. It is a white, water-soluble solid. [1] Being a diprotic acid, its acid-base properties is described by two equilibria: H 2 AsO − 4 + H 2 O ⇌ HAsO 2−
This reaction generates glucose-6-arsenate and 6-arsenogluconate, which act as analogs for glucose-6-phosphate and 6-phosphogluconate. [40] At the substrate level, during glycolysis , glucose-6-arsenate binds as a substrate to glucose-6-phosphate dehydrogenase, and also inhibits hexokinase through negative feedback. [ 40 ]
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 many people.
Sodium dihydrogen arsenate is a colorless solid that is highly toxic. The salt is the conjugate base of arsenic acid: H 3 AsO 4 ⇌ H 2 AsO − 4 + H + (K 1 = 10 −2.19) In the laboratory, it is prepared in this way, crystallizing from a hot saturated aqueous solution, where it is highly soluble when hot (75.3 g in 100 mL at 100 °C). It is ...
Samarium(III) arsenate can be produced by reacting sodium arsenate (Na 3 AsO 4) and samarium(III) chloride (SmCl 3) in solution: [4] Na 3 AsO 4 + SmCl 3 → 3 NaCl + SmAsO 4 ↓ References
Sodium arsenite can be inhaled or absorbed through the skin. Along with its known carcinogenic and teratogenic effects, contact with the substance can yield symptoms such as skin irritation, burns, itching, thickened skin, rash, loss of pigment, poor appetite, a metallic or garlic taste, stomach pain, nausea, vomiting, diarrhea, convulsions, decreased blood pressure, and headache.
Disodium methyl arsenate (DSMA) is the organoarsenic compound with the formula CH3AsO3Na2. It is a colorless, water-soluble solid derived from methanearsonic acid. It is used as a herbicide. [1] Tradenames include Metharsinat, Arrhenal, Disomear, Metharsan, Stenosine, Tonarsan, Tonarsin, Arsinyl, Arsynal, and Diarsen.
