Chromic acid Chemical Properties,Uses,Production

General Description

Chromic acid is a dark purplish red solid. Chromic acid is soluble in water with the release of heat. The material itself is noncombustible but Chromic acid will accelerate the burning of combustible materials. Its solution is corrosive to metals and tissue.

Air & Water Reactions

Water soluble.

Reactivity Profile

A very powerful oxidizing agent, confirmed human carcinogen. Upon contact with reducing reagents Chromic acid can cause a violent explosion, in contact with organic matter Chromic acid may cause a violent oxidation leading to ignition. Dangerously reactive with acetone, alcohols, alkali metals (sodium, potassium), ammonia, arsenic, dimethylformamide, hydrogen sulfide, phosphorus, peroxyformic acid, pyridine, selenium, sulfur, and many other chemicals [Sax, 9th ed., 1996, p. 852]. When mixed with sulfuric acid for glass cleaning operations, used solution in closed bottle may explode due to internal pressure of carbon dioxide arising from contamination by carbon compounds [Bryson, W. R., Chem. Brit., 1975, 11, p. 377].

Health Hazard

Very irritating to eyes and respiratory tract. Ingestion causes severe gastrointestinal symptoms. Contact with eyes or skin causes burns; prolonged contact produces dermatitis (``chrome sores'').

Fire Hazard

Behavior in Fire: Containers may explode
