What is the name of the formula Na3AsO3?
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
What is redox in remediation?
•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

Is arsenate polar?
Yes. Arsenate (AsO43−) is an ionic compound and therefore polar.
How 1000 ppm solution of arsenite prepared from sodiumarsenite?
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
Arsenate acts as uncoupling agent for oxidative phosphorylation?
Yes. During glycolysis, arsenate which has a similar structure to phosphate replaces it from glyceraldehyde-3-phosphate to form an unstable arsenate anhydride( 1-arsenato-3-phospho-d-glycerate) that hydrolyzes to form arsenate and 3-phosphoglycerate. In the absence of phosphate, ATP is not formed in the reaction. ADP-arsenate is formed from ADP and arsenate in the presence of succinate. The formation of easily hydrolyzable ADP-arsenate complex uncouples oxidative phosphorylation and causes arsenolysis.
