Arsenate is a compound comprised of arsenic that has a +3 oxidation state. Arsenate is usually an ion but can also become a compound containing that ion with esters or salts made of arsenic acid.
Sodium ortho-arsenite, although the name is often shortened to sodium arsenite. It contains the AsO33- ion ortho-arsenite ion. Arsenic has oxidation number +3. Confusingly there is another compound NaAsO2 sodium meta-arsenite whose name is also shortened to sodium arsenite. This contains a polymeric meta-arsenite ion (AsO2-)n . Again arsenic has oxidation number of +3
FeAsO3 is the chemical formula of the iron (III) arsenite.
•Knowing the redox chemistry of an element is critical to remediating fluids •Arsenic -Arsenate is toxic, arsenite is dangerously so •Chromium -Hexavalent chromium is bad •A return to a more natural, less-hazardous state
Ba+2 C2H3O2-1
An arsenite is an oxyanion of trivalent arsenic, especially the AsO33- anion or protonated derivatives.
sodium arsenate
The formula for germanium arsenate is GeAsO4.
1 ppm means 1 mg/l so 1000 ppm means 1000 mg/l or 1gm/l , FW of sodium arsenite NaAsO2 is 130 ans As is 75 75 gm of arsenite is present in 130 gm sodium arsenite 1 gm---------------will be---------130/75= 1.73 gm so if 1.73 gm of sodium arsenite is present in 1 litre of water it makes 1000 ppm solution of arsenite
The name is tripotassium hexachlorocobaltate.
The chemical formula for ammonium arsenite is (NH4)3AsO3. It is composed of three ammonium ions (NH4+) and one arsenite ion (AsO3-) in the compound.
Magnesium dihydrogen arsenate is the name. The formula is Mg(H2AsO4)2
The reaction between arsenic trioxide (As2O3) and sodium hydroxide (NaOH) results in the formation of sodium arsenite (Na3AsO3) and water. The balanced chemical equation is: As2O3 + 6NaOH → 2Na3AsO3 + 3H2O
