Chromic acid Usage And Synthesis
Chemical PropertiesChromic acid is a dark purplish-red odorless flakes or crystalline powder
UsesChemicals (chromates, oxidizing agents, catalysts), chromium-plating intermediate, medicine (caustic), process engraving, anodizing, ceramic glazes, colored glass, metal cleaning, inks, tanning, paints, textile mordant, etchant for plastics.
DefinitionThe name is in common use, although the true chromic acid, H2CrO4, exists only in solution.
Definitionchromic acid: A hypothetical acid,H2CrO4, known only in chromatesalts.
General DescriptionChromic acid is a dark purplish red solid, exists only in solution. The hydrate of chromiumoxide, it is used in electroplating baths. 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 ReactionsWater soluble.
Reactivity ProfileA 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].
HazardA human carcinogen. A poison. Corrosive to skin. Powerful oxidizing agent, may explode on contact with reducing agents, may ignite on contact with organic materials. Upper respiratory tract irritant.
Health HazardVery 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 HazardBehavior in Fire: Containers may explode
Safety ProfileConfirmed human carcinogen. Poison by subcutaneous route. Mutation data reported. A powerful oxidzer. A powerful irritant of skin, eyes, and mucous membranes. Can cause a dermatitis, bronchoasthma, “chrome holes,” damage to the eyes. Dangerously reactive. Incompatible with acetic acid, acetic anhydride, tetrahydronaphthalene, acetone, alcohols, alkali metals, ammonia, arsenic, bromine penta fluoride, butyric acid, n,ndimethylformamide, hydrogen sulfide, peroxyformic acid, phosphorus, potassium hexacyanoferrate, pyridme, selenium
Potential Exposuren chromium plating; medicine, ceramic glazers, and paints.
First aidMove victim to fresh air. Call 911 or emergency Medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, Chromic(VI) Acid 833 Avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion, or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy
