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]. |
