Melting Point:197 °C
Boiling Point:330ºC
Flash Point:250ºC
Water Solubility:H2O: Highly soluble
Storage Conditions:Do not store near combustible materials. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away fr
Vapor Pressure:Very low
Flammability characteristics:CrO3: Noncombustible Solid, but will accelerate the burning of combustible materials.
Odor:Odorless
PH:Dissolves in water to form a weak acid
Experimental Properties:Chromium trioxide, CrO3, contains hexavalent chromium. Its molecular weight is 100.01. It is also known as red oxide of chromium, chromic anhydride, chromic acid anhydride and, erroneously, chromic acid.|Heat of fusion: 37.7 cal/g|Deliquescent|Hexavalent chromium is linked to oxygen and is a powerful oxidizer, but it does not form coordination compounds, and is easily reduced to chromium trioxide. /Hexavalent chromium/|For more Other Experimental Properties (Complete) data for CHROMIC TRIOXIDE (8 total), please visit the HSDB record page.
Air and Water Reactions:Deliquescent. Water soluble, giving acidic solutions.
Reactive Group:Anhydrides
Reactivity Alerts:Strong Oxidizing Agent
Reactivity Profile:CHROMIUM TRIOXIDE is a powerful oxidizing agent. Can react violently upon contact with reducing reagents, including organic matter, leading to ignition or explosion. 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]. Noncombustible but can accelerate the burning of combustible materials. Sufficient heat may be generated from the reaction with combustible materials to ignite the mass. Aqueous solutions corrode many metals rapidly. Often mixed with sulfuric acid to make "cleaning solution" for glass. Used cleaning solution in closed bottles may explode due to the build up of gaseous carbon dioxide arising from oxidation of organic impurities [Bryson, W. R., Chem. Brit., 1975, 11, p. 377].
Autoignition Temperature:May ignite organic materials on contact. (USCG, 1999)
Flammable Limits:CrO3: Noncombustible Solid, but will accelerate the burning of combustible materials.
