Solubility:The solubility of ferric arsenate (FeAsO4) was studied at 25-73 deg C and pH 3.5-11 with regard to removal of arsenic from waste waters; solubility is negligible in neutral soln. However, it was 4.4X10-6 and 3.8X10-2 g-ion/L at 73 deg C and pH 3 and 11, respectively.
Specification:

1.General Description: Ferrous arsenate is toxic by ingestion and inhalation and is a strong irritant.
2.Reactivity Profile:Ferrous arsenate has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.
3.Health Hazard :Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
4.Fire Hazard :Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways.

Report:

Arsenic and its compounds are on the Community Right-To-Know List.
