ZINC ARSENATE Chemical Properties,Usage,Production

General Description

A mixture of two compounds. Various forms of zinc arsenate are known. Zinc orthoarsenate Zn(AsO4)2. 8H2O is a white odorless water-insoluble powder. Zinc metaarsenite is a white water-soluble powder. Highly toxic by ingestion and inhalation.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

ZINC ARSENATE-ZINC ARSENITE MIXTURE 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.

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.

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.
